Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 148988, here are decompositions:
- 31 + 148957 = 148988
- 61 + 148927 = 148988
- 67 + 148921 = 148988
- 97 + 148891 = 148988
- 127 + 148861 = 148988
- 241 + 148747 = 148988
- 277 + 148711 = 148988
- 349 + 148639 = 148988
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 148,988 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 148988 first appears in π at position 350,591 of the decimal expansion (the 350,591ordinal-suffix:st 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.
