Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31547604, here are decompositions:

13 + 31547591 = 31547604
47 + 31547557 = 31547604
73 + 31547531 = 31547604
97 + 31547507 = 31547604
163 + 31547441 = 31547604
191 + 31547413 = 31547604
307 + 31547297 = 31547604
317 + 31547287 = 31547604

Showing the first eight; more decompositions exist.
