Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31501608, here are decompositions:

41 + 31501567 = 31501608
71 + 31501537 = 31501608
181 + 31501427 = 31501608
199 + 31501409 = 31501608
277 + 31501331 = 31501608
379 + 31501229 = 31501608
389 + 31501219 = 31501608
409 + 31501199 = 31501608

Showing the first eight; more decompositions exist.
