Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31610644, here are decompositions:

3 + 31610641 = 31610644
5 + 31610639 = 31610644
71 + 31610573 = 31610644
83 + 31610561 = 31610644
251 + 31610393 = 31610644
281 + 31610363 = 31610644
311 + 31610333 = 31610644
353 + 31610291 = 31610644

Showing the first eight; more decompositions exist.
