Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31610292, here are decompositions:

5 + 31610287 = 31610292
13 + 31610279 = 31610292
23 + 31610269 = 31610292
61 + 31610231 = 31610292
79 + 31610213 = 31610292
149 + 31610143 = 31610292
151 + 31610141 = 31610292
179 + 31610113 = 31610292

Showing the first eight; more decompositions exist.
