Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31555364, here are decompositions:

37 + 31555327 = 31555364
67 + 31555297 = 31555364
97 + 31555267 = 31555364
193 + 31555171 = 31555364
223 + 31555141 = 31555364
271 + 31555093 = 31555364
283 + 31555081 = 31555364
523 + 31554841 = 31555364

Showing the first eight; more decompositions exist.
