Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31497564, here are decompositions:

5 + 31497559 = 31497564
13 + 31497551 = 31497564
17 + 31497547 = 31497564
23 + 31497541 = 31497564
37 + 31497527 = 31497564
41 + 31497523 = 31497564
73 + 31497491 = 31497564
97 + 31497467 = 31497564

Showing the first eight; more decompositions exist.
