Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31540022, here are decompositions:

13 + 31540009 = 31540022
373 + 31539649 = 31540022
379 + 31539643 = 31540022
439 + 31539583 = 31540022
499 + 31539523 = 31540022
523 + 31539499 = 31540022
601 + 31539421 = 31540022
673 + 31539349 = 31540022

Showing the first eight; more decompositions exist.
