Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31484466, here are decompositions:

5 + 31484461 = 31484466
17 + 31484449 = 31484466
53 + 31484413 = 31484466
89 + 31484377 = 31484466
103 + 31484363 = 31484466
107 + 31484359 = 31484466
113 + 31484353 = 31484466
127 + 31484339 = 31484466

Showing the first eight; more decompositions exist.
