Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 472722, here are decompositions:

11 + 472711 = 472722
13 + 472709 = 472722
31 + 472691 = 472722
53 + 472669 = 472722
79 + 472643 = 472722
83 + 472639 = 472722
149 + 472573 = 472722
163 + 472559 = 472722

Showing the first eight; more decompositions exist.
