Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31468694, here are decompositions:

97 + 31468597 = 31468694
151 + 31468543 = 31468694
223 + 31468471 = 31468694
241 + 31468453 = 31468694
463 + 31468231 = 31468694
547 + 31468147 = 31468694
727 + 31467967 = 31468694
757 + 31467937 = 31468694

Showing the first eight; more decompositions exist.
