Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31547560, here are decompositions:

3 + 31547557 = 31547560
29 + 31547531 = 31547560
41 + 31547519 = 31547560
53 + 31547507 = 31547560
71 + 31547489 = 31547560
89 + 31547471 = 31547560
101 + 31547459 = 31547560
257 + 31547303 = 31547560

Showing the first eight; more decompositions exist.
