Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31484590, here are decompositions:

47 + 31484543 = 31484590
173 + 31484417 = 31484590
227 + 31484363 = 31484590
251 + 31484339 = 31484590
353 + 31484237 = 31484590
383 + 31484207 = 31484590
461 + 31484129 = 31484590
509 + 31484081 = 31484590

Showing the first eight; more decompositions exist.
