Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31465558, here are decompositions:

11 + 31465547 = 31465558
29 + 31465529 = 31465558
107 + 31465451 = 31465558
167 + 31465391 = 31465558
269 + 31465289 = 31465558
617 + 31464941 = 31465558
827 + 31464731 = 31465558
857 + 31464701 = 31465558

Showing the first eight; more decompositions exist.
