Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31566376, here are decompositions:

29 + 31566347 = 31566376
47 + 31566329 = 31566376
59 + 31566317 = 31566376
89 + 31566287 = 31566376
239 + 31566137 = 31566376
293 + 31566083 = 31566376
383 + 31565993 = 31566376
683 + 31565693 = 31566376

Showing the first eight; more decompositions exist.
