Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31468664, here are decompositions:

67 + 31468597 = 31468664
193 + 31468471 = 31468664
211 + 31468453 = 31468664
421 + 31468243 = 31468664
433 + 31468231 = 31468664
463 + 31468201 = 31468664
727 + 31467937 = 31468664
811 + 31467853 = 31468664

Showing the first eight; more decompositions exist.
