Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31501834, here are decompositions:

3 + 31501831 = 31501834
11 + 31501823 = 31501834
53 + 31501781 = 31501834
83 + 31501751 = 31501834
107 + 31501727 = 31501834
113 + 31501721 = 31501834
173 + 31501661 = 31501834
251 + 31501583 = 31501834

Showing the first eight; more decompositions exist.
