Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31540922, here are decompositions:

109 + 31540813 = 31540922
139 + 31540783 = 31540922
199 + 31540723 = 31540922
223 + 31540699 = 31540922
229 + 31540693 = 31540922
271 + 31540651 = 31540922
349 + 31540573 = 31540922
421 + 31540501 = 31540922

Showing the first eight; more decompositions exist.
