Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31484430, here are decompositions:

13 + 31484417 = 31484430
17 + 31484413 = 31484430
53 + 31484377 = 31484430
67 + 31484363 = 31484430
71 + 31484359 = 31484430
113 + 31484317 = 31484430
127 + 31484303 = 31484430
149 + 31484281 = 31484430

Showing the first eight; more decompositions exist.
