Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31484724, here are decompositions:

13 + 31484711 = 31484724
97 + 31484627 = 31484724
107 + 31484617 = 31484724
181 + 31484543 = 31484724
191 + 31484533 = 31484724
211 + 31484513 = 31484724
263 + 31484461 = 31484724
307 + 31484417 = 31484724

Showing the first eight; more decompositions exist.
