Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31468934, here are decompositions:

31 + 31468903 = 31468934
73 + 31468861 = 31468934
157 + 31468777 = 31468934
337 + 31468597 = 31468934
463 + 31468471 = 31468934
487 + 31468447 = 31468934
691 + 31468243 = 31468934
733 + 31468201 = 31468934

Showing the first eight; more decompositions exist.
