Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31547222, here are decompositions:

13 + 31547209 = 31547222
19 + 31547203 = 31547222
61 + 31547161 = 31547222
79 + 31547143 = 31547222
241 + 31546981 = 31547222
313 + 31546909 = 31547222
331 + 31546891 = 31547222
379 + 31546843 = 31547222

Showing the first eight; more decompositions exist.
