Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31465792, here are decompositions:

3 + 31465789 = 31465792
11 + 31465781 = 31465792
131 + 31465661 = 31465792
173 + 31465619 = 31465792
191 + 31465601 = 31465792
263 + 31465529 = 31465792
311 + 31465481 = 31465792
401 + 31465391 = 31465792

Showing the first eight; more decompositions exist.
