Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31542722, here are decompositions:

19 + 31542703 = 31542722
109 + 31542613 = 31542722
163 + 31542559 = 31542722
199 + 31542523 = 31542722
283 + 31542439 = 31542722
331 + 31542391 = 31542722
349 + 31542373 = 31542722
619 + 31542103 = 31542722

Showing the first eight; more decompositions exist.
