Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31522292, here are decompositions:

73 + 31522219 = 31522292
163 + 31522129 = 31522292
271 + 31522021 = 31522292
313 + 31521979 = 31522292
409 + 31521883 = 31522292
463 + 31521829 = 31522292
499 + 31521793 = 31522292
619 + 31521673 = 31522292

Showing the first eight; more decompositions exist.
