Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31547566, here are decompositions:

47 + 31547519 = 31547566
59 + 31547507 = 31547566
107 + 31547459 = 31547566
227 + 31547339 = 31547566
263 + 31547303 = 31547566
269 + 31547297 = 31547566
389 + 31547177 = 31547566
419 + 31547147 = 31547566

Showing the first eight; more decompositions exist.
