Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31610542, here are decompositions:

3 + 31610539 = 31610542
23 + 31610519 = 31610542
149 + 31610393 = 31610542
179 + 31610363 = 31610542
251 + 31610291 = 31610542
263 + 31610279 = 31610542
311 + 31610231 = 31610542
401 + 31610141 = 31610542

Showing the first eight; more decompositions exist.
