Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31461548, here are decompositions:

31 + 31461517 = 31461548
61 + 31461487 = 31461548
67 + 31461481 = 31461548
199 + 31461349 = 31461548
367 + 31461181 = 31461548
421 + 31461127 = 31461548
499 + 31461049 = 31461548
541 + 31461007 = 31461548

Showing the first eight; more decompositions exist.
