Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31496702, here are decompositions:

31 + 31496671 = 31496702
103 + 31496599 = 31496702
109 + 31496593 = 31496702
151 + 31496551 = 31496702
163 + 31496539 = 31496702
283 + 31496419 = 31496702
313 + 31496389 = 31496702
331 + 31496371 = 31496702

Showing the first eight; more decompositions exist.
