Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31522190, here are decompositions:

61 + 31522129 = 31522190
199 + 31521991 = 31522190
211 + 31521979 = 31522190
307 + 31521883 = 31522190
397 + 31521793 = 31522190
523 + 31521667 = 31522190
541 + 31521649 = 31522190
547 + 31521643 = 31522190

Showing the first eight; more decompositions exist.
