Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31484966, here are decompositions:

103 + 31484863 = 31484966
127 + 31484839 = 31484966
349 + 31484617 = 31484966
397 + 31484569 = 31484966
433 + 31484533 = 31484966
463 + 31484503 = 31484966
607 + 31484359 = 31484966
613 + 31484353 = 31484966

Showing the first eight; more decompositions exist.
