Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31601284, here are decompositions:

17 + 31601267 = 31601284
233 + 31601051 = 31601284
401 + 31600883 = 31601284
461 + 31600823 = 31601284
467 + 31600817 = 31601284
563 + 31600721 = 31601284
761 + 31600523 = 31601284
773 + 31600511 = 31601284

Showing the first eight; more decompositions exist.
