Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31494446, here are decompositions:

3 + 31494443 = 31494446
7 + 31494439 = 31494446
19 + 31494427 = 31494446
199 + 31494247 = 31494446
349 + 31494097 = 31494446
367 + 31494079 = 31494446
457 + 31493989 = 31494446
463 + 31493983 = 31494446

Showing the first eight; more decompositions exist.
