Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31464956, here are decompositions:

73 + 31464883 = 31464956
199 + 31464757 = 31464956
307 + 31464649 = 31464956
337 + 31464619 = 31464956
379 + 31464577 = 31464956
409 + 31464547 = 31464956
463 + 31464493 = 31464956
547 + 31464409 = 31464956

Showing the first eight; more decompositions exist.
