Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 149004, here are decompositions:
- 7 + 148997 = 149004
- 13 + 148991 = 149004
- 43 + 148961 = 149004
- 47 + 148957 = 149004
- 71 + 148933 = 149004
- 73 + 148931 = 149004
- 83 + 148921 = 149004
- 113 + 148891 = 149004
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 149,004 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 149004 first appears in π at position 506,344 of the decimal expansion (the 506,344ordinal-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.
