Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31610008, here are decompositions:

41 + 31609967 = 31610008
71 + 31609937 = 31610008
137 + 31609871 = 31610008
239 + 31609769 = 31610008
317 + 31609691 = 31610008
347 + 31609661 = 31610008
431 + 31609577 = 31610008
461 + 31609547 = 31610008

Showing the first eight; more decompositions exist.
