Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31461814, here are decompositions:

3 + 31461811 = 31461814
23 + 31461791 = 31461814
53 + 31461761 = 31461814
71 + 31461743 = 31461814
173 + 31461641 = 31461814
257 + 31461557 = 31461814
281 + 31461533 = 31461814
401 + 31461413 = 31461814

Showing the first eight; more decompositions exist.
