Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31550672, here are decompositions:

61 + 31550611 = 31550672
73 + 31550599 = 31550672
79 + 31550593 = 31550672
103 + 31550569 = 31550672
163 + 31550509 = 31550672
193 + 31550479 = 31550672
211 + 31550461 = 31550672
271 + 31550401 = 31550672

Showing the first eight; more decompositions exist.
