Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31501058, here are decompositions:

19 + 31501039 = 31501058
79 + 31500979 = 31501058
139 + 31500919 = 31501058
241 + 31500817 = 31501058
367 + 31500691 = 31501058
409 + 31500649 = 31501058
499 + 31500559 = 31501058
571 + 31500487 = 31501058

Showing the first eight; more decompositions exist.
