Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31483186, here are decompositions:

17 + 31483169 = 31483186
23 + 31483163 = 31483186
89 + 31483097 = 31483186
239 + 31482947 = 31483186
347 + 31482839 = 31483186
353 + 31482833 = 31483186
443 + 31482743 = 31483186
479 + 31482707 = 31483186

Showing the first eight; more decompositions exist.
