Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31464986, here are decompositions:

13 + 31464973 = 31464986
19 + 31464967 = 31464986
103 + 31464883 = 31464986
199 + 31464787 = 31464986
229 + 31464757 = 31464986
277 + 31464709 = 31464986
337 + 31464649 = 31464986
367 + 31464619 = 31464986

Showing the first eight; more decompositions exist.
