Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31501796, here are decompositions:

37 + 31501759 = 31501796
97 + 31501699 = 31501796
127 + 31501669 = 31501796
163 + 31501633 = 31501796
229 + 31501567 = 31501796
349 + 31501447 = 31501796
397 + 31501399 = 31501796
409 + 31501387 = 31501796

Showing the first eight; more decompositions exist.
