Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31464896, here are decompositions:

13 + 31464883 = 31464896
109 + 31464787 = 31464896
139 + 31464757 = 31464896
277 + 31464619 = 31464896
349 + 31464547 = 31464896
433 + 31464463 = 31464896
457 + 31464439 = 31464896
487 + 31464409 = 31464896

Showing the first eight; more decompositions exist.
