Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31462650, here are decompositions:

41 + 31462609 = 31462650
47 + 31462603 = 31462650
59 + 31462591 = 31462650
61 + 31462589 = 31462650
67 + 31462583 = 31462650
71 + 31462579 = 31462650
73 + 31462577 = 31462650
97 + 31462553 = 31462650

Showing the first eight; more decompositions exist.
