Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1020802, here are decompositions:

5 + 1020797 = 1020802
23 + 1020779 = 1020802
59 + 1020743 = 1020802
113 + 1020689 = 1020802
311 + 1020491 = 1020802
383 + 1020419 = 1020802
389 + 1020413 = 1020802
401 + 1020401 = 1020802

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 1,020,802 and was likely granted around 1911.

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