Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31464082, here are decompositions:

3 + 31464079 = 31464082
173 + 31463909 = 31464082
191 + 31463891 = 31464082
233 + 31463849 = 31464082
239 + 31463843 = 31464082
401 + 31463681 = 31464082
491 + 31463591 = 31464082
563 + 31463519 = 31464082

Showing the first eight; more decompositions exist.
