Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31522922, here are decompositions:

229 + 31522693 = 31522922
331 + 31522591 = 31522922
373 + 31522549 = 31522922
463 + 31522459 = 31522922
1039 + 31521883 = 31522922
1093 + 31521829 = 31522922
1129 + 31521793 = 31522922
1249 + 31521673 = 31522922

Showing the first eight; more decompositions exist.
