Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31464622, here are decompositions:

3 + 31464619 = 31464622
5 + 31464617 = 31464622
41 + 31464581 = 31464622
113 + 31464509 = 31464622
179 + 31464443 = 31464622
263 + 31464359 = 31464622
281 + 31464341 = 31464622
353 + 31464269 = 31464622

Showing the first eight; more decompositions exist.
