Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31547564, here are decompositions:

7 + 31547557 = 31547564
151 + 31547413 = 31547564
277 + 31547287 = 31547564
283 + 31547281 = 31547564
421 + 31547143 = 31547564
463 + 31547101 = 31547564
487 + 31547077 = 31547564
577 + 31546987 = 31547564

Showing the first eight; more decompositions exist.
