Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31537796, here are decompositions:

79 + 31537717 = 31537796
109 + 31537687 = 31537796
193 + 31537603 = 31537796
223 + 31537573 = 31537796
457 + 31537339 = 31537796
487 + 31537309 = 31537796
523 + 31537273 = 31537796
643 + 31537153 = 31537796

Showing the first eight; more decompositions exist.
