Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31547294, here are decompositions:

7 + 31547287 = 31547294
13 + 31547281 = 31547294
151 + 31547143 = 31547294
193 + 31547101 = 31547294
307 + 31546987 = 31547294
313 + 31546981 = 31547294
433 + 31546861 = 31547294
463 + 31546831 = 31547294

Showing the first eight; more decompositions exist.
