Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31547594, here are decompositions:

3 + 31547591 = 31547594
37 + 31547557 = 31547594
181 + 31547413 = 31547594
277 + 31547317 = 31547594
307 + 31547287 = 31547594
313 + 31547281 = 31547594
433 + 31547161 = 31547594
607 + 31546987 = 31547594

Showing the first eight; more decompositions exist.
