Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31467684, here are decompositions:

7 + 31467677 = 31467684
37 + 31467647 = 31467684
97 + 31467587 = 31467684
113 + 31467571 = 31467684
151 + 31467533 = 31467684
181 + 31467503 = 31467684
251 + 31467433 = 31467684
317 + 31467367 = 31467684

Showing the first eight; more decompositions exist.
