Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31610254, here are decompositions:

17 + 31610237 = 31610254
23 + 31610231 = 31610254
41 + 31610213 = 31610254
83 + 31610171 = 31610254
113 + 31610141 = 31610254
173 + 31610081 = 31610254
191 + 31610063 = 31610254
281 + 31609973 = 31610254

Showing the first eight; more decompositions exist.
