Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31505796, here are decompositions:

13 + 31505783 = 31505796
29 + 31505767 = 31505796
59 + 31505737 = 31505796
67 + 31505729 = 31505796
73 + 31505723 = 31505796
103 + 31505693 = 31505796
137 + 31505659 = 31505796
139 + 31505657 = 31505796

Showing the first eight; more decompositions exist.
