Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31468126, here are decompositions:

29 + 31468097 = 31468126
59 + 31468067 = 31468126
113 + 31468013 = 31468126
227 + 31467899 = 31468126
233 + 31467893 = 31468126
317 + 31467809 = 31468126
359 + 31467767 = 31468126
449 + 31467677 = 31468126

Showing the first eight; more decompositions exist.
