Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 175820, here are decompositions:

37 + 175783 = 175820
61 + 175759 = 175820
67 + 175753 = 175820
97 + 175723 = 175820
157 + 175663 = 175820
199 + 175621 = 175820
277 + 175543 = 175820
367 + 175453 = 175820

Showing the first eight; more decompositions exist.
