Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31496750, here are decompositions:

31 + 31496719 = 31496750
73 + 31496677 = 31496750
79 + 31496671 = 31496750
139 + 31496611 = 31496750
151 + 31496599 = 31496750
157 + 31496593 = 31496750
163 + 31496587 = 31496750
199 + 31496551 = 31496750

Showing the first eight; more decompositions exist.
