Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31601846, here are decompositions:

37 + 31601809 = 31601846
79 + 31601767 = 31601846
103 + 31601743 = 31601846
139 + 31601707 = 31601846
277 + 31601569 = 31601846
307 + 31601539 = 31601846
337 + 31601509 = 31601846
373 + 31601473 = 31601846

Showing the first eight; more decompositions exist.
