Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31461774, here are decompositions:

11 + 31461763 = 31461774
13 + 31461761 = 31461774
31 + 31461743 = 31461774
37 + 31461737 = 31461774
101 + 31461673 = 31461774
241 + 31461533 = 31461774
251 + 31461523 = 31461774
257 + 31461517 = 31461774

Showing the first eight; more decompositions exist.
