Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31464856, here are decompositions:

29 + 31464827 = 31464856
47 + 31464809 = 31464856
239 + 31464617 = 31464856
347 + 31464509 = 31464856
587 + 31464269 = 31464856
719 + 31464137 = 31464856
809 + 31464047 = 31464856
947 + 31463909 = 31464856

Showing the first eight; more decompositions exist.
