Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31564924, here are decompositions:

3 + 31564921 = 31564924
5 + 31564919 = 31564924
71 + 31564853 = 31564924
263 + 31564661 = 31564924
311 + 31564613 = 31564924
491 + 31564433 = 31564924
563 + 31564361 = 31564924
593 + 31564331 = 31564924

Showing the first eight; more decompositions exist.
