Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31450022, here are decompositions:

31 + 31449991 = 31450022
151 + 31449871 = 31450022
199 + 31449823 = 31450022
271 + 31449751 = 31450022
283 + 31449739 = 31450022
349 + 31449673 = 31450022
433 + 31449589 = 31450022
523 + 31449499 = 31450022

Showing the first eight; more decompositions exist.
