Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31522064, here are decompositions:

3 + 31522061 = 31522064
43 + 31522021 = 31522064
73 + 31521991 = 31522064
181 + 31521883 = 31522064
271 + 31521793 = 31522064
397 + 31521667 = 31522064
421 + 31521643 = 31522064
523 + 31521541 = 31522064

Showing the first eight; more decompositions exist.
