Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 146988, here are decompositions:
- 5 + 146983 = 146988
- 11 + 146977 = 146988
- 47 + 146941 = 146988
- 67 + 146921 = 146988
- 71 + 146917 = 146988
- 97 + 146891 = 146988
- 131 + 146857 = 146988
- 139 + 146849 = 146988
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 146,988 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 146988 first appears in π at position 780,123 of the decimal expansion (the 780,123ordinal-suffix:rd 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.
