Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31555514, here are decompositions:

127 + 31555387 = 31555514
271 + 31555243 = 31555514
373 + 31555141 = 31555514
421 + 31555093 = 31555514
433 + 31555081 = 31555514
631 + 31554883 = 31555514
673 + 31554841 = 31555514
691 + 31554823 = 31555514

Showing the first eight; more decompositions exist.
