Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31483348, here are decompositions:

41 + 31483307 = 31483348
131 + 31483217 = 31483348
179 + 31483169 = 31483348
251 + 31483097 = 31483348
401 + 31482947 = 31483348
509 + 31482839 = 31483348
569 + 31482779 = 31483348
587 + 31482761 = 31483348

Showing the first eight; more decompositions exist.
