Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31501762, here are decompositions:

3 + 31501759 = 31501762
11 + 31501751 = 31501762
41 + 31501721 = 31501762
101 + 31501661 = 31501762
179 + 31501583 = 31501762
239 + 31501523 = 31501762
353 + 31501409 = 31501762
359 + 31501403 = 31501762

Showing the first eight; more decompositions exist.
