Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31492268, here are decompositions:

7 + 31492261 = 31492268
541 + 31491727 = 31492268
571 + 31491697 = 31492268
607 + 31491661 = 31492268
631 + 31491637 = 31492268
757 + 31491511 = 31492268
937 + 31491331 = 31492268
1069 + 31491199 = 31492268

Showing the first eight; more decompositions exist.
