Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31610374, here are decompositions:

11 + 31610363 = 31610374
41 + 31610333 = 31610374
83 + 31610291 = 31610374
137 + 31610237 = 31610374
233 + 31610141 = 31610374
281 + 31610093 = 31610374
293 + 31610081 = 31610374
311 + 31610063 = 31610374

Showing the first eight; more decompositions exist.
