Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31480682, here are decompositions:

43 + 31480639 = 31480682
61 + 31480621 = 31480682
241 + 31480441 = 31480682
313 + 31480369 = 31480682
661 + 31480021 = 31480682
733 + 31479949 = 31480682
853 + 31479829 = 31480682
1033 + 31479649 = 31480682

Showing the first eight; more decompositions exist.
