Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31484654, here are decompositions:

7 + 31484647 = 31484654
37 + 31484617 = 31484654
151 + 31484503 = 31484654
193 + 31484461 = 31484654
241 + 31484413 = 31484654
277 + 31484377 = 31484654
337 + 31484317 = 31484654
373 + 31484281 = 31484654

Showing the first eight; more decompositions exist.
