Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31610674, here are decompositions:

101 + 31610573 = 31610674
113 + 31610561 = 31610674
281 + 31610393 = 31610674
311 + 31610363 = 31610674
383 + 31610291 = 31610674
443 + 31610231 = 31610674
461 + 31610213 = 31610674
503 + 31610171 = 31610674

Showing the first eight; more decompositions exist.
