Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31496664, here are decompositions:

53 + 31496611 = 31496664
71 + 31496593 = 31496664
97 + 31496567 = 31496664
113 + 31496551 = 31496664
127 + 31496537 = 31496664
223 + 31496441 = 31496664
293 + 31496371 = 31496664
347 + 31496317 = 31496664

Showing the first eight; more decompositions exist.
