Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31464926, here are decompositions:

43 + 31464883 = 31464926
139 + 31464787 = 31464926
277 + 31464649 = 31464926
307 + 31464619 = 31464926
349 + 31464577 = 31464926
379 + 31464547 = 31464926
433 + 31464493 = 31464926
463 + 31464463 = 31464926

Showing the first eight; more decompositions exist.
