Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31484924, here are decompositions:

13 + 31484911 = 31484924
61 + 31484863 = 31484924
103 + 31484821 = 31484924
127 + 31484797 = 31484924
277 + 31484647 = 31484924
307 + 31484617 = 31484924
421 + 31484503 = 31484924
463 + 31484461 = 31484924

Showing the first eight; more decompositions exist.
