Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8656874, here are decompositions:

3 + 8656871 = 8656874
43 + 8656831 = 8656874
67 + 8656807 = 8656874
73 + 8656801 = 8656874
271 + 8656603 = 8656874
313 + 8656561 = 8656874
337 + 8656537 = 8656874
397 + 8656477 = 8656874

Showing the first eight; more decompositions exist.
