Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31466784, here are decompositions:

31 + 31466753 = 31466784
53 + 31466731 = 31466784
71 + 31466713 = 31466784
113 + 31466671 = 31466784
127 + 31466657 = 31466784
157 + 31466627 = 31466784
197 + 31466587 = 31466784
281 + 31466503 = 31466784

Showing the first eight; more decompositions exist.
