Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31465132, here are decompositions:

3 + 31465129 = 31465132
71 + 31465061 = 31465132
191 + 31464941 = 31465132
311 + 31464821 = 31465132
401 + 31464731 = 31465132
431 + 31464701 = 31465132
773 + 31464359 = 31465132
863 + 31464269 = 31465132

Showing the first eight; more decompositions exist.
