Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31501710, here are decompositions:

11 + 31501699 = 31501710
41 + 31501669 = 31501710
89 + 31501621 = 31501710
127 + 31501583 = 31501710
173 + 31501537 = 31501710
179 + 31501531 = 31501710
263 + 31501447 = 31501710
277 + 31501433 = 31501710

Showing the first eight; more decompositions exist.
