Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31462826, here are decompositions:

19 + 31462807 = 31462826
67 + 31462759 = 31462826
79 + 31462747 = 31462826
97 + 31462729 = 31462826
103 + 31462723 = 31462826
223 + 31462603 = 31462826
463 + 31462363 = 31462826
487 + 31462339 = 31462826

Showing the first eight; more decompositions exist.
