Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 139604, here are decompositions:
- 7 + 139597 = 139604
- 13 + 139591 = 139604
- 67 + 139537 = 139604
- 103 + 139501 = 139604
- 181 + 139423 = 139604
- 211 + 139393 = 139604
- 271 + 139333 = 139604
- 307 + 139297 = 139604
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 139,604 and was likely granted around 1872.
Patent numbers below 100,000 are excluded as too ambiguous; modern numbering currently reaches roughly 12.5 million.
The digit sequence 139604 first appears in π at position 735,224 of the decimal expansion (the 735,224ordinal-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.
