Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31547124, here are decompositions:

23 + 31547101 = 31547124
31 + 31547093 = 31547124
47 + 31547077 = 31547124
61 + 31547063 = 31547124
127 + 31546997 = 31547124
137 + 31546987 = 31547124
211 + 31546913 = 31547124
233 + 31546891 = 31547124

Showing the first eight; more decompositions exist.
