Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31501276, here are decompositions:

29 + 31501247 = 31501276
47 + 31501229 = 31501276
239 + 31501037 = 31501276
353 + 31500923 = 31501276
467 + 31500809 = 31501276
479 + 31500797 = 31501276
503 + 31500773 = 31501276
509 + 31500767 = 31501276

Showing the first eight; more decompositions exist.
