Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31445314, here are decompositions:

41 + 31445273 = 31445314
71 + 31445243 = 31445314
83 + 31445231 = 31445314
113 + 31445201 = 31445314
281 + 31445033 = 31445314
443 + 31444871 = 31445314
587 + 31444727 = 31445314
653 + 31444661 = 31445314

Showing the first eight; more decompositions exist.
