Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31462680, here are decompositions:

31 + 31462649 = 31462680
71 + 31462609 = 31462680
89 + 31462591 = 31462680
97 + 31462583 = 31462680
101 + 31462579 = 31462680
103 + 31462577 = 31462680
107 + 31462573 = 31462680
127 + 31462553 = 31462680

Showing the first eight; more decompositions exist.
