Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31547556, here are decompositions:

17 + 31547539 = 31547556
37 + 31547519 = 31547556
67 + 31547489 = 31547556
97 + 31547459 = 31547556
107 + 31547449 = 31547556
199 + 31547357 = 31547556
239 + 31547317 = 31547556
269 + 31547287 = 31547556

Showing the first eight; more decompositions exist.
