Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31467088, here are decompositions:

5 + 31467083 = 31467088
17 + 31467071 = 31467088
89 + 31466999 = 31467088
137 + 31466951 = 31467088
239 + 31466849 = 31467088
431 + 31466657 = 31467088
461 + 31466627 = 31467088
491 + 31466597 = 31467088

Showing the first eight; more decompositions exist.
