Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31465366, here are decompositions:

3 + 31465363 = 31465366
173 + 31465193 = 31465366
419 + 31464947 = 31465366
557 + 31464809 = 31465366
809 + 31464557 = 31465366
857 + 31464509 = 31465366
1097 + 31464269 = 31465366
1217 + 31464149 = 31465366

Showing the first eight; more decompositions exist.
