Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31467686, here are decompositions:

97 + 31467589 = 31467686
127 + 31467559 = 31467686
457 + 31467229 = 31467686
487 + 31467199 = 31467686
619 + 31467067 = 31467686
709 + 31466977 = 31467686
787 + 31466899 = 31467686
829 + 31466857 = 31467686

Showing the first eight; more decompositions exist.
