Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31462760, here are decompositions:

3 + 31462757 = 31462760
13 + 31462747 = 31462760
31 + 31462729 = 31462760
37 + 31462723 = 31462760
151 + 31462609 = 31462760
157 + 31462603 = 31462760
181 + 31462579 = 31462760
229 + 31462531 = 31462760

Showing the first eight; more decompositions exist.
