Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31609330, here are decompositions:

41 + 31609289 = 31609330
101 + 31609229 = 31609330
107 + 31609223 = 31609330
239 + 31609091 = 31609330
251 + 31609079 = 31609330
281 + 31609049 = 31609330
359 + 31608971 = 31609330
419 + 31608911 = 31609330

Showing the first eight; more decompositions exist.
