Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31607776, here are decompositions:

29 + 31607747 = 31607776
59 + 31607717 = 31607776
89 + 31607687 = 31607776
197 + 31607579 = 31607776
353 + 31607423 = 31607776
419 + 31607357 = 31607776
449 + 31607327 = 31607776
467 + 31607309 = 31607776

Showing the first eight; more decompositions exist.
