Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31495124, here are decompositions:

7 + 31495117 = 31495124
61 + 31495063 = 31495124
181 + 31494943 = 31495124
307 + 31494817 = 31495124
433 + 31494691 = 31495124
487 + 31494637 = 31495124
541 + 31494583 = 31495124
571 + 31494553 = 31495124

Showing the first eight; more decompositions exist.
