Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31496708, here are decompositions:

31 + 31496677 = 31496708
37 + 31496671 = 31496708
97 + 31496611 = 31496708
109 + 31496599 = 31496708
157 + 31496551 = 31496708
337 + 31496371 = 31496708
379 + 31496329 = 31496708
487 + 31496221 = 31496708

Showing the first eight; more decompositions exist.
