Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31464876, here are decompositions:

67 + 31464809 = 31464876
89 + 31464787 = 31464876
167 + 31464709 = 31464876
227 + 31464649 = 31464876
257 + 31464619 = 31464876
367 + 31464509 = 31464876
383 + 31464493 = 31464876
433 + 31464443 = 31464876

Showing the first eight; more decompositions exist.
