Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31501362, here are decompositions:

29 + 31501333 = 31501362
31 + 31501331 = 31501362
41 + 31501321 = 31501362
59 + 31501303 = 31501362
131 + 31501231 = 31501362
163 + 31501199 = 31501362
271 + 31501091 = 31501362
281 + 31501081 = 31501362

Showing the first eight; more decompositions exist.
