Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31462610, here are decompositions:

7 + 31462603 = 31462610
19 + 31462591 = 31462610
31 + 31462579 = 31462610
37 + 31462573 = 31462610
79 + 31462531 = 31462610
103 + 31462507 = 31462610
139 + 31462471 = 31462610
229 + 31462381 = 31462610

Showing the first eight; more decompositions exist.
