Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31609502, here are decompositions:

3 + 31609499 = 31609502
109 + 31609393 = 31609502
163 + 31609339 = 31609502
271 + 31609231 = 31609502
313 + 31609189 = 31609502
409 + 31609093 = 31609502
619 + 31608883 = 31609502
709 + 31608793 = 31609502

Showing the first eight; more decompositions exist.
