Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31484656, here are decompositions:

29 + 31484627 = 31484656
113 + 31484543 = 31484656
239 + 31484417 = 31484656
293 + 31484363 = 31484656
317 + 31484339 = 31484656
353 + 31484303 = 31484656
389 + 31484267 = 31484656
419 + 31484237 = 31484656

Showing the first eight; more decompositions exist.
