Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31610242, here are decompositions:

5 + 31610237 = 31610242
11 + 31610231 = 31610242
29 + 31610213 = 31610242
71 + 31610171 = 31610242
101 + 31610141 = 31610242
149 + 31610093 = 31610242
179 + 31610063 = 31610242
233 + 31610009 = 31610242

Showing the first eight; more decompositions exist.
