Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31610794, here are decompositions:

3 + 31610791 = 31610794
23 + 31610771 = 31610794
53 + 31610741 = 31610794
71 + 31610723 = 31610794
233 + 31610561 = 31610794
401 + 31610393 = 31610794
431 + 31610363 = 31610794
461 + 31610333 = 31610794

Showing the first eight; more decompositions exist.
