Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31610194, here are decompositions:

23 + 31610171 = 31610194
53 + 31610141 = 31610194
101 + 31610093 = 31610194
113 + 31610081 = 31610194
131 + 31610063 = 31610194
227 + 31609967 = 31610194
257 + 31609937 = 31610194
263 + 31609931 = 31610194

Showing the first eight; more decompositions exist.
