Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31464792, here are decompositions:

5 + 31464787 = 31464792
11 + 31464781 = 31464792
61 + 31464731 = 31464792
83 + 31464709 = 31464792
173 + 31464619 = 31464792
211 + 31464581 = 31464792
283 + 31464509 = 31464792
311 + 31464481 = 31464792

Showing the first eight; more decompositions exist.
