Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31502050, here are decompositions:

71 + 31501979 = 31502050
113 + 31501937 = 31502050
137 + 31501913 = 31502050
227 + 31501823 = 31502050
269 + 31501781 = 31502050
389 + 31501661 = 31502050
431 + 31501619 = 31502050
467 + 31501583 = 31502050

Showing the first eight; more decompositions exist.
