Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31501496, here are decompositions:

97 + 31501399 = 31501496
109 + 31501387 = 31501496
163 + 31501333 = 31501496
193 + 31501303 = 31501496
277 + 31501219 = 31501496
379 + 31501117 = 31501496
457 + 31501039 = 31501496
487 + 31501009 = 31501496

Showing the first eight; more decompositions exist.
