Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 120644, here are decompositions:
- 3 + 120641 = 120644
- 37 + 120607 = 120644
- 67 + 120577 = 120644
- 313 + 120331 = 120644
- 367 + 120277 = 120644
- 397 + 120247 = 120644
- 421 + 120223 = 120644
- 463 + 120181 = 120644
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 120,644 and was likely granted around 1871.
Patent numbers below 100,000 are excluded as too ambiguous; modern numbering currently reaches roughly 12.5 million.
The digit sequence 120644 first appears in π at position 106,524 of the decimal expansion (the 106,524ordinal-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.
