Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31501614, here are decompositions:

31 + 31501583 = 31501614
47 + 31501567 = 31501614
83 + 31501531 = 31501614
167 + 31501447 = 31501614
181 + 31501433 = 31501614
211 + 31501403 = 31501614
227 + 31501387 = 31501614
281 + 31501333 = 31501614

Showing the first eight; more decompositions exist.
