Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31555076, here are decompositions:

13 + 31555063 = 31555076
127 + 31554949 = 31555076
193 + 31554883 = 31555076
337 + 31554739 = 31555076
367 + 31554709 = 31555076
409 + 31554667 = 31555076
439 + 31554637 = 31555076
457 + 31554619 = 31555076

Showing the first eight; more decompositions exist.
