Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 155604, here are decompositions:
- 5 + 155599 = 155604
- 11 + 155593 = 155604
- 23 + 155581 = 155604
- 47 + 155557 = 155604
- 67 + 155537 = 155604
- 83 + 155521 = 155604
- 103 + 155501 = 155604
- 131 + 155473 = 155604
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 155,604 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 155604 first appears in π at position 431,519 of the decimal expansion (the 431,519ordinal-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.
