Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31484464, here are decompositions:

3 + 31484461 = 31484464
47 + 31484417 = 31484464
101 + 31484363 = 31484464
197 + 31484267 = 31484464
227 + 31484237 = 31484464
257 + 31484207 = 31484464
383 + 31484081 = 31484464
587 + 31483877 = 31484464

Showing the first eight; more decompositions exist.
