Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31484742, here are decompositions:

31 + 31484711 = 31484742
43 + 31484699 = 31484742
173 + 31484569 = 31484742
199 + 31484543 = 31484742
229 + 31484513 = 31484742
239 + 31484503 = 31484742
281 + 31484461 = 31484742
293 + 31484449 = 31484742

Showing the first eight; more decompositions exist.
