Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31501382, here are decompositions:

61 + 31501321 = 31501382
79 + 31501303 = 31501382
151 + 31501231 = 31501382
163 + 31501219 = 31501382
181 + 31501201 = 31501382
373 + 31501009 = 31501382
463 + 31500919 = 31501382
691 + 31500691 = 31501382

Showing the first eight; more decompositions exist.
