Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31464854, here are decompositions:

67 + 31464787 = 31464854
73 + 31464781 = 31464854
97 + 31464757 = 31464854
277 + 31464577 = 31464854
283 + 31464571 = 31464854
307 + 31464547 = 31464854
373 + 31464481 = 31464854
433 + 31464421 = 31464854

Showing the first eight; more decompositions exist.
