Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31508534, here are decompositions:

7 + 31508527 = 31508534
73 + 31508461 = 31508534
223 + 31508311 = 31508534
307 + 31508227 = 31508534
331 + 31508203 = 31508534
433 + 31508101 = 31508534
457 + 31508077 = 31508534
613 + 31507921 = 31508534

Showing the first eight; more decompositions exist.
