Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31608722, here are decompositions:

193 + 31608529 = 31608722
241 + 31608481 = 31608722
373 + 31608349 = 31608722
421 + 31608301 = 31608722
631 + 31608091 = 31608722
661 + 31608061 = 31608722
709 + 31608013 = 31608722
751 + 31607971 = 31608722

Showing the first eight; more decompositions exist.
