Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31555796, here are decompositions:

79 + 31555717 = 31555796
163 + 31555633 = 31555796
193 + 31555603 = 31555796
367 + 31555429 = 31555796
409 + 31555387 = 31555796
499 + 31555297 = 31555796
733 + 31555063 = 31555796
907 + 31554889 = 31555796

Showing the first eight; more decompositions exist.
