Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31462216, here are decompositions:

83 + 31462133 = 31462216
89 + 31462127 = 31462216
113 + 31462103 = 31462216
239 + 31461977 = 31462216
293 + 31461923 = 31462216
479 + 31461737 = 31462216
563 + 31461653 = 31462216
647 + 31461569 = 31462216

Showing the first eight; more decompositions exist.
