Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31555592, here are decompositions:

43 + 31555549 = 31555592
163 + 31555429 = 31555592
349 + 31555243 = 31555592
421 + 31555171 = 31555592
499 + 31555093 = 31555592
571 + 31555021 = 31555592
631 + 31554961 = 31555592
643 + 31554949 = 31555592

Showing the first eight; more decompositions exist.
