Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31480594, here are decompositions:

227 + 31480367 = 31480594
491 + 31480103 = 31480594
503 + 31480091 = 31480594
647 + 31479947 = 31480594
773 + 31479821 = 31480594
857 + 31479737 = 31480594
947 + 31479647 = 31480594
1103 + 31479491 = 31480594

Showing the first eight; more decompositions exist.
