Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31547418, here are decompositions:

5 + 31547413 = 31547418
61 + 31547357 = 31547418
79 + 31547339 = 31547418
101 + 31547317 = 31547418
131 + 31547287 = 31547418
137 + 31547281 = 31547418
151 + 31547267 = 31547418
157 + 31547261 = 31547418

Showing the first eight; more decompositions exist.
