Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31462822, here are decompositions:

11 + 31462811 = 31462822
29 + 31462793 = 31462822
71 + 31462751 = 31462822
173 + 31462649 = 31462822
233 + 31462589 = 31462822
239 + 31462583 = 31462822
269 + 31462553 = 31462822
383 + 31462439 = 31462822

Showing the first eight; more decompositions exist.
