Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31502914, here are decompositions:

17 + 31502897 = 31502914
137 + 31502777 = 31502914
227 + 31502687 = 31502914
353 + 31502561 = 31502914
431 + 31502483 = 31502914
701 + 31502213 = 31502914
977 + 31501937 = 31502914
1091 + 31501823 = 31502914

Showing the first eight; more decompositions exist.
