Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31494488, here are decompositions:

19 + 31494469 = 31494488
61 + 31494427 = 31494488
241 + 31494247 = 31494488
331 + 31494157 = 31494488
397 + 31494091 = 31494488
409 + 31494079 = 31494488
499 + 31493989 = 31494488
547 + 31493941 = 31494488

Showing the first eight; more decompositions exist.
