Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31609022, here are decompositions:

139 + 31608883 = 31609022
199 + 31608823 = 31609022
229 + 31608793 = 31609022
433 + 31608589 = 31609022
541 + 31608481 = 31609022
673 + 31608349 = 31609022
751 + 31608271 = 31609022
853 + 31608169 = 31609022

Showing the first eight; more decompositions exist.
