Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31467488, here are decompositions:

7 + 31467481 = 31467488
229 + 31467259 = 31467488
307 + 31467181 = 31467488
331 + 31467157 = 31467488
421 + 31467067 = 31467488
499 + 31466989 = 31467488
631 + 31466857 = 31467488
739 + 31466749 = 31467488

Showing the first eight; more decompositions exist.
