Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31502404, here are decompositions:

41 + 31502363 = 31502404
71 + 31502333 = 31502404
191 + 31502213 = 31502404
257 + 31502147 = 31502404
467 + 31501937 = 31502404
491 + 31501913 = 31502404
653 + 31501751 = 31502404
677 + 31501727 = 31502404

Showing the first eight; more decompositions exist.
