Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31596518, here are decompositions:

7 + 31596511 = 31596518
127 + 31596391 = 31596518
139 + 31596379 = 31596518
211 + 31596307 = 31596518
367 + 31596151 = 31596518
397 + 31596121 = 31596518
787 + 31595731 = 31596518
907 + 31595611 = 31596518

Showing the first eight; more decompositions exist.
