Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31569376, here are decompositions:

17 + 31569359 = 31569376
29 + 31569347 = 31569376
89 + 31569287 = 31569376
239 + 31569137 = 31569376
269 + 31569107 = 31569376
317 + 31569059 = 31569376
467 + 31568909 = 31569376
479 + 31568897 = 31569376

Showing the first eight; more decompositions exist.
