Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31462668, here are decompositions:

19 + 31462649 = 31462668
59 + 31462609 = 31462668
79 + 31462589 = 31462668
89 + 31462579 = 31462668
137 + 31462531 = 31462668
197 + 31462471 = 31462668
227 + 31462441 = 31462668
229 + 31462439 = 31462668

Showing the first eight; more decompositions exist.
