Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31501262, here are decompositions:

31 + 31501231 = 31501262
43 + 31501219 = 31501262
61 + 31501201 = 31501262
181 + 31501081 = 31501262
223 + 31501039 = 31501262
283 + 31500979 = 31501262
409 + 31500853 = 31501262
571 + 31500691 = 31501262

Showing the first eight; more decompositions exist.
