Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31610454, here are decompositions:

17 + 31610437 = 31610454
41 + 31610413 = 31610454
61 + 31610393 = 31610454
101 + 31610353 = 31610454
137 + 31610317 = 31610454
163 + 31610291 = 31610454
167 + 31610287 = 31610454
223 + 31610231 = 31610454

Showing the first eight; more decompositions exist.
