Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31468082, here are decompositions:

229 + 31467853 = 31468082
271 + 31467811 = 31468082
523 + 31467559 = 31468082
601 + 31467481 = 31468082
823 + 31467259 = 31468082
853 + 31467229 = 31468082
883 + 31467199 = 31468082
1093 + 31466989 = 31468082

Showing the first eight; more decompositions exist.
