Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31501352, here are decompositions:

19 + 31501333 = 31501352
31 + 31501321 = 31501352
151 + 31501201 = 31501352
271 + 31501081 = 31501352
313 + 31501039 = 31501352
373 + 31500979 = 31501352
433 + 31500919 = 31501352
499 + 31500853 = 31501352

Showing the first eight; more decompositions exist.
