Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31462790, here are decompositions:

19 + 31462771 = 31462790
31 + 31462759 = 31462790
43 + 31462747 = 31462790
61 + 31462729 = 31462790
67 + 31462723 = 31462790
181 + 31462609 = 31462790
199 + 31462591 = 31462790
211 + 31462579 = 31462790

Showing the first eight; more decompositions exist.
