Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31609424, here are decompositions:

31 + 31609393 = 31609424
43 + 31609381 = 31609424
157 + 31609267 = 31609424
193 + 31609231 = 31609424
211 + 31609213 = 31609424
307 + 31609117 = 31609424
313 + 31609111 = 31609424
331 + 31609093 = 31609424

Showing the first eight; more decompositions exist.
