Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31484716, here are decompositions:

5 + 31484711 = 31484716
17 + 31484699 = 31484716
89 + 31484627 = 31484716
173 + 31484543 = 31484716
353 + 31484363 = 31484716
449 + 31484267 = 31484716
479 + 31484237 = 31484716
509 + 31484207 = 31484716

Showing the first eight; more decompositions exist.
