Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8611504, here are decompositions:
- 3 + 8611501 = 8611504
- 17 + 8611487 = 8611504
- 71 + 8611433 = 8611504
- 101 + 8611403 = 8611504
- 173 + 8611331 = 8611504
- 197 + 8611307 = 8611504
- 257 + 8611247 = 8611504
- 353 + 8611151 = 8611504
Showing the first eight; more decompositions exist.

This number falls in the range of US utility patent numbers. If it's a patent, it would be issued as US 8,611,504 and was likely granted around 2013.
Patent numbers below 100,000 are excluded as too ambiguous; modern numbering currently reaches roughly 12.5 million.
The digit sequence 8611504 first appears in π at position 769,332 of the decimal expansion (the 769,332ordinal-suffix:nd digit after the integer 3).
Search range: the first 1,000,000 fractional digits of π. Any 6-digit-or-shorter string is virtually guaranteed to appear in there — the more interesting signal is the position.
