Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31453126, here are decompositions:

149 + 31452977 = 31453126
443 + 31452683 = 31453126
449 + 31452677 = 31453126
503 + 31452623 = 31453126
587 + 31452539 = 31453126
599 + 31452527 = 31453126
953 + 31452173 = 31453126
1217 + 31451909 = 31453126

Showing the first eight; more decompositions exist.
