Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31556194, here are decompositions:

53 + 31556141 = 31556194
113 + 31556081 = 31556194
227 + 31555967 = 31556194
317 + 31555877 = 31556194
353 + 31555841 = 31556194
431 + 31555763 = 31556194
563 + 31555631 = 31556194
587 + 31555607 = 31556194

Showing the first eight; more decompositions exist.
