Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31624256, here are decompositions:

109 + 31624147 = 31624256
127 + 31624129 = 31624256
277 + 31623979 = 31624256
439 + 31623817 = 31624256
733 + 31623523 = 31624256
757 + 31623499 = 31624256
883 + 31623373 = 31624256
919 + 31623337 = 31624256

Showing the first eight; more decompositions exist.
