Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31502766, here are decompositions:

5 + 31502761 = 31502766
23 + 31502743 = 31502766
67 + 31502699 = 31502766
79 + 31502687 = 31502766
107 + 31502659 = 31502766
179 + 31502587 = 31502766
227 + 31502539 = 31502766
233 + 31502533 = 31502766

Showing the first eight; more decompositions exist.
