Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31547588, here are decompositions:

31 + 31547557 = 31547588
109 + 31547479 = 31547588
139 + 31547449 = 31547588
271 + 31547317 = 31547588
307 + 31547281 = 31547588
379 + 31547209 = 31547588
487 + 31547101 = 31547588
601 + 31546987 = 31547588

Showing the first eight; more decompositions exist.
