Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31614746, here are decompositions:

13 + 31614733 = 31614746
43 + 31614703 = 31614746
103 + 31614643 = 31614746
199 + 31614547 = 31614746
223 + 31614523 = 31614746
463 + 31614283 = 31614746
547 + 31614199 = 31614746
613 + 31614133 = 31614746

Showing the first eight; more decompositions exist.
