Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31468874, here are decompositions:

13 + 31468861 = 31468874
97 + 31468777 = 31468874
277 + 31468597 = 31468874
331 + 31468543 = 31468874
421 + 31468453 = 31468874
631 + 31468243 = 31468874
643 + 31468231 = 31468874
673 + 31468201 = 31468874

Showing the first eight; more decompositions exist.
