Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31501322, here are decompositions:

19 + 31501303 = 31501322
103 + 31501219 = 31501322
241 + 31501081 = 31501322
283 + 31501039 = 31501322
313 + 31501009 = 31501322
631 + 31500691 = 31501322
673 + 31500649 = 31501322
733 + 31500589 = 31501322

Showing the first eight; more decompositions exist.
