Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31501514, here are decompositions:

67 + 31501447 = 31501514
127 + 31501387 = 31501514
181 + 31501333 = 31501514
193 + 31501321 = 31501514
211 + 31501303 = 31501514
283 + 31501231 = 31501514
313 + 31501201 = 31501514
397 + 31501117 = 31501514

Showing the first eight; more decompositions exist.
