Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31508084, here are decompositions:

7 + 31508077 = 31508084
67 + 31508017 = 31508084
103 + 31507981 = 31508084
163 + 31507921 = 31508084
313 + 31507771 = 31508084
331 + 31507753 = 31508084
523 + 31507561 = 31508084
577 + 31507507 = 31508084

Showing the first eight; more decompositions exist.
