Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31484768, here are decompositions:

151 + 31484617 = 31484768
199 + 31484569 = 31484768
307 + 31484461 = 31484768
409 + 31484359 = 31484768
487 + 31484281 = 31484768
607 + 31484161 = 31484768
709 + 31484059 = 31484768
787 + 31483981 = 31484768

Showing the first eight; more decompositions exist.
