Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31556344, here are decompositions:

3 + 31556341 = 31556344
41 + 31556303 = 31556344
101 + 31556243 = 31556344
263 + 31556081 = 31556344
311 + 31556033 = 31556344
353 + 31555991 = 31556344
467 + 31555877 = 31556344
503 + 31555841 = 31556344

Showing the first eight; more decompositions exist.
