Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31468832, here are decompositions:

379 + 31468453 = 31468832
433 + 31468399 = 31468832
463 + 31468369 = 31468832
601 + 31468231 = 31468832
631 + 31468201 = 31468832
673 + 31468159 = 31468832
883 + 31467949 = 31468832
1021 + 31467811 = 31468832

Showing the first eight; more decompositions exist.
