Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31609382, here are decompositions:

43 + 31609339 = 31609382
151 + 31609231 = 31609382
193 + 31609189 = 31609382
271 + 31609111 = 31609382
349 + 31609033 = 31609382
499 + 31608883 = 31609382
661 + 31608721 = 31609382
853 + 31608529 = 31609382

Showing the first eight; more decompositions exist.
