Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31502110, here are decompositions:

11 + 31502099 = 31502110
131 + 31501979 = 31502110
173 + 31501937 = 31502110
197 + 31501913 = 31502110
359 + 31501751 = 31502110
383 + 31501727 = 31502110
389 + 31501721 = 31502110
449 + 31501661 = 31502110

Showing the first eight; more decompositions exist.
