Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31464998, here are decompositions:

7 + 31464991 = 31464998
31 + 31464967 = 31464998
211 + 31464787 = 31464998
241 + 31464757 = 31464998
349 + 31464649 = 31464998
379 + 31464619 = 31464998
421 + 31464577 = 31464998
547 + 31464451 = 31464998

Showing the first eight; more decompositions exist.
