Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31468170, here are decompositions:

11 + 31468159 = 31468170
23 + 31468147 = 31468170
73 + 31468097 = 31468170
103 + 31468067 = 31468170
157 + 31468013 = 31468170
233 + 31467937 = 31468170
271 + 31467899 = 31468170
277 + 31467893 = 31468170

Showing the first eight; more decompositions exist.
