Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31467808, here are decompositions:

41 + 31467767 = 31467808
89 + 31467719 = 31467808
131 + 31467677 = 31467808
257 + 31467551 = 31467808
269 + 31467539 = 31467808
311 + 31467497 = 31467808
389 + 31467419 = 31467808
419 + 31467389 = 31467808

Showing the first eight; more decompositions exist.
