Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31484426, here are decompositions:

13 + 31484413 = 31484426
67 + 31484359 = 31484426
73 + 31484353 = 31484426
109 + 31484317 = 31484426
223 + 31484203 = 31484426
283 + 31484143 = 31484426
367 + 31484059 = 31484426
499 + 31483927 = 31484426

Showing the first eight; more decompositions exist.
