Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31468036, here are decompositions:

23 + 31468013 = 31468036
53 + 31467983 = 31468036
137 + 31467899 = 31468036
227 + 31467809 = 31468036
269 + 31467767 = 31468036
317 + 31467719 = 31468036
359 + 31467677 = 31468036
389 + 31467647 = 31468036

Showing the first eight; more decompositions exist.
