Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31502634, here are decompositions:

47 + 31502587 = 31502634
71 + 31502563 = 31502634
73 + 31502561 = 31502634
101 + 31502533 = 31502634
151 + 31502483 = 31502634
193 + 31502441 = 31502634
263 + 31502371 = 31502634
271 + 31502363 = 31502634

Showing the first eight; more decompositions exist.
