Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31609010, here are decompositions:

73 + 31608937 = 31609010
127 + 31608883 = 31609010
157 + 31608853 = 31609010
193 + 31608817 = 31609010
283 + 31608727 = 31609010
313 + 31608697 = 31609010
421 + 31608589 = 31609010
661 + 31608349 = 31609010

Showing the first eight; more decompositions exist.
