Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31547364, here are decompositions:

7 + 31547357 = 31547364
47 + 31547317 = 31547364
61 + 31547303 = 31547364
67 + 31547297 = 31547364
83 + 31547281 = 31547364
97 + 31547267 = 31547364
103 + 31547261 = 31547364
263 + 31547101 = 31547364

Showing the first eight; more decompositions exist.
