Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31540654, here are decompositions:

3 + 31540651 = 31540654
11 + 31540643 = 31540654
17 + 31540637 = 31540654
23 + 31540631 = 31540654
311 + 31540343 = 31540654
443 + 31540211 = 31540654
491 + 31540163 = 31540654
641 + 31540013 = 31540654

Showing the first eight; more decompositions exist.
