Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31610248, here are decompositions:

11 + 31610237 = 31610248
17 + 31610231 = 31610248
107 + 31610141 = 31610248
167 + 31610081 = 31610248
239 + 31610009 = 31610248
281 + 31609967 = 31610248
311 + 31609937 = 31610248
317 + 31609931 = 31610248

Showing the first eight; more decompositions exist.
