Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31501526, here are decompositions:

3 + 31501523 = 31501526
79 + 31501447 = 31501526
127 + 31501399 = 31501526
139 + 31501387 = 31501526
193 + 31501333 = 31501526
223 + 31501303 = 31501526
307 + 31501219 = 31501526
409 + 31501117 = 31501526

Showing the first eight; more decompositions exist.
