Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31609374, here are decompositions:

107 + 31609267 = 31609374
151 + 31609223 = 31609374
257 + 31609117 = 31609374
263 + 31609111 = 31609374
281 + 31609093 = 31609374
283 + 31609091 = 31609374
421 + 31608953 = 31609374
457 + 31608917 = 31609374

Showing the first eight; more decompositions exist.
