Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31458446, here are decompositions:

43 + 31458403 = 31458446
67 + 31458379 = 31458446
73 + 31458373 = 31458446
277 + 31458169 = 31458446
433 + 31458013 = 31458446
457 + 31457989 = 31458446
577 + 31457869 = 31458446
709 + 31457737 = 31458446

Showing the first eight; more decompositions exist.
