Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31559476, here are decompositions:

5 + 31559471 = 31559476
29 + 31559447 = 31559476
59 + 31559417 = 31559476
257 + 31559219 = 31559476
269 + 31559207 = 31559476
383 + 31559093 = 31559476
449 + 31559027 = 31559476
479 + 31558997 = 31559476

Showing the first eight; more decompositions exist.
