Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 147504, here are decompositions:
- 17 + 147487 = 147504
- 23 + 147481 = 147504
- 47 + 147457 = 147504
- 53 + 147451 = 147504
- 103 + 147401 = 147504
- 107 + 147397 = 147504
- 113 + 147391 = 147504
- 127 + 147377 = 147504
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 147,504 and was likely granted around 1873.
Patent numbers below 100,000 are excluded as too ambiguous; modern numbering currently reaches roughly 12.5 million.
The digit sequence 147504 first appears in π at position 47,486 of the decimal expansion (the 47,486ordinal-suffix:th 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.
