Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31555736, here are decompositions:

19 + 31555717 = 31555736
73 + 31555663 = 31555736
103 + 31555633 = 31555736
193 + 31555543 = 31555736
307 + 31555429 = 31555736
349 + 31555387 = 31555736
409 + 31555327 = 31555736
439 + 31555297 = 31555736

Showing the first eight; more decompositions exist.
