Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31456496, here are decompositions:

67 + 31456429 = 31456496
277 + 31456219 = 31456496
373 + 31456123 = 31456496
397 + 31456099 = 31456496
607 + 31455889 = 31456496
619 + 31455877 = 31456496
769 + 31455727 = 31456496
859 + 31455637 = 31456496

Showing the first eight; more decompositions exist.
