Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31484506, here are decompositions:

3 + 31484503 = 31484506
89 + 31484417 = 31484506
167 + 31484339 = 31484506
239 + 31484267 = 31484506
269 + 31484237 = 31484506
587 + 31483919 = 31484506
593 + 31483913 = 31484506
617 + 31483889 = 31484506

Showing the first eight; more decompositions exist.
