Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31455014, here are decompositions:

43 + 31454971 = 31455014
61 + 31454953 = 31455014
277 + 31454737 = 31455014
313 + 31454701 = 31455014
631 + 31454383 = 31455014
751 + 31454263 = 31455014
823 + 31454191 = 31455014
853 + 31454161 = 31455014

Showing the first eight; more decompositions exist.
