Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31468412, here are decompositions:

13 + 31468399 = 31468412
43 + 31468369 = 31468412
181 + 31468231 = 31468412
211 + 31468201 = 31468412
463 + 31467949 = 31468412
601 + 31467811 = 31468412
691 + 31467721 = 31468412
823 + 31467589 = 31468412

Showing the first eight; more decompositions exist.
