Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31547090, here are decompositions:

13 + 31547077 = 31547090
103 + 31546987 = 31547090
109 + 31546981 = 31547090
181 + 31546909 = 31547090
199 + 31546891 = 31547090
229 + 31546861 = 31547090
277 + 31546813 = 31547090
283 + 31546807 = 31547090

Showing the first eight; more decompositions exist.
