Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31462568, here are decompositions:

37 + 31462531 = 31462568
61 + 31462507 = 31462568
97 + 31462471 = 31462568
127 + 31462441 = 31462568
211 + 31462357 = 31462568
229 + 31462339 = 31462568
499 + 31462069 = 31462568
547 + 31462021 = 31462568

Showing the first eight; more decompositions exist.
