Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31530362, here are decompositions:

13 + 31530349 = 31530362
151 + 31530211 = 31530362
181 + 31530181 = 31530362
439 + 31529923 = 31530362
463 + 31529899 = 31530362
613 + 31529749 = 31530362
691 + 31529671 = 31530362
733 + 31529629 = 31530362

Showing the first eight; more decompositions exist.
