Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31522076, here are decompositions:

97 + 31521979 = 31522076
193 + 31521883 = 31522076
283 + 31521793 = 31522076
337 + 31521739 = 31522076
409 + 31521667 = 31522076
433 + 31521643 = 31522076
577 + 31521499 = 31522076
643 + 31521433 = 31522076

Showing the first eight; more decompositions exist.
