Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31610564, here are decompositions:

3 + 31610561 = 31610564
43 + 31610521 = 31610564
61 + 31610503 = 31610564
127 + 31610437 = 31610564
151 + 31610413 = 31610564
211 + 31610353 = 31610564
277 + 31610287 = 31610564
367 + 31610197 = 31610564

Showing the first eight; more decompositions exist.
