Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31465372, here are decompositions:

83 + 31465289 = 31465372
149 + 31465223 = 31465372
179 + 31465193 = 31465372
311 + 31465061 = 31465372
431 + 31464941 = 31465372
563 + 31464809 = 31465372
641 + 31464731 = 31465372
863 + 31464509 = 31465372

Showing the first eight; more decompositions exist.
