Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31501046, here are decompositions:

7 + 31501039 = 31501046
37 + 31501009 = 31501046
67 + 31500979 = 31501046
79 + 31500967 = 31501046
127 + 31500919 = 31501046
193 + 31500853 = 31501046
229 + 31500817 = 31501046
397 + 31500649 = 31501046

Showing the first eight; more decompositions exist.
