Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31484574, here are decompositions:

5 + 31484569 = 31484574
31 + 31484543 = 31484574
41 + 31484533 = 31484574
61 + 31484513 = 31484574
71 + 31484503 = 31484574
113 + 31484461 = 31484574
157 + 31484417 = 31484574
197 + 31484377 = 31484574

Showing the first eight; more decompositions exist.
