Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31467784, here are decompositions:

17 + 31467767 = 31467784
107 + 31467677 = 31467784
137 + 31467647 = 31467784
191 + 31467593 = 31467784
197 + 31467587 = 31467784
233 + 31467551 = 31467784
251 + 31467533 = 31467784
281 + 31467503 = 31467784

Showing the first eight; more decompositions exist.
