Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31596906, here are decompositions:

7 + 31596899 = 31596906
17 + 31596889 = 31596906
23 + 31596883 = 31596906
59 + 31596847 = 31596906
67 + 31596839 = 31596906
109 + 31596797 = 31596906
113 + 31596793 = 31596906
137 + 31596769 = 31596906

Showing the first eight; more decompositions exist.
