Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31547084, here are decompositions:

7 + 31547077 = 31547084
97 + 31546987 = 31547084
103 + 31546981 = 31547084
193 + 31546891 = 31547084
223 + 31546861 = 31547084
241 + 31546843 = 31547084
271 + 31546813 = 31547084
277 + 31546807 = 31547084

Showing the first eight; more decompositions exist.
