Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 146878, here are decompositions:
- 29 + 146849 = 146878
- 41 + 146837 = 146878
- 59 + 146819 = 146878
- 71 + 146807 = 146878
- 101 + 146777 = 146878
- 197 + 146681 = 146878
- 239 + 146639 = 146878
- 269 + 146609 = 146878
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 146,878 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 146878 first appears in π at position 377,968 of the decimal expansion (the 377,968ordinal-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.
