Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 146148, here are decompositions:
- 7 + 146141 = 146148
- 31 + 146117 = 146148
- 71 + 146077 = 146148
- 89 + 146059 = 146148
- 97 + 146051 = 146148
- 127 + 146021 = 146148
- 137 + 146011 = 146148
- 139 + 146009 = 146148
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 146,148 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 146148 first appears in π at position 59,212 of the decimal expansion (the 59,212ordinal-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.
