Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31468166, here are decompositions:

7 + 31468159 = 31468166
19 + 31468147 = 31468166
139 + 31468027 = 31468166
199 + 31467967 = 31468166
229 + 31467937 = 31468166
313 + 31467853 = 31468166
337 + 31467829 = 31468166
439 + 31467727 = 31468166

Showing the first eight; more decompositions exist.
