Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31522864, here are decompositions:

17 + 31522847 = 31522864
41 + 31522823 = 31522864
251 + 31522613 = 31522864
281 + 31522583 = 31522864
311 + 31522553 = 31522864
431 + 31522433 = 31522864
491 + 31522373 = 31522864
587 + 31522277 = 31522864

Showing the first eight; more decompositions exist.
