Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31610664, here are decompositions:

23 + 31610641 = 31610664
83 + 31610581 = 31610664
101 + 31610563 = 31610664
103 + 31610561 = 31610664
227 + 31610437 = 31610664
251 + 31610413 = 31610664
271 + 31610393 = 31610664
311 + 31610353 = 31610664

Showing the first eight; more decompositions exist.
