Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 145004, here are decompositions:

31 + 144973 = 145004
37 + 144967 = 145004
43 + 144961 = 145004
73 + 144931 = 145004
157 + 144847 = 145004
241 + 144763 = 145004
337 + 144667 = 145004
421 + 144583 = 145004

Showing the first eight; more decompositions exist.

Possible US patent number

This number falls in the range of US utility patent numbers. If it's a patent, it would be issued as US 145,004 and was likely granted around 1873.

Patent numbers below 100,000 are excluded as too ambiguous; modern numbering currently reaches roughly 12.5 million.
