Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 148942, here are decompositions:
- 11 + 148931 = 148942
- 29 + 148913 = 148942
- 83 + 148859 = 148942
- 89 + 148853 = 148942
- 113 + 148829 = 148942
- 149 + 148793 = 148942
- 179 + 148763 = 148942
- 251 + 148691 = 148942
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 148,942 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 148942 first appears in π at position 942,958 of the decimal expansion (the 942,958ordinal-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.
