Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8657798, here are decompositions:

31 + 8657767 = 8657798
67 + 8657731 = 8657798
229 + 8657569 = 8657798
241 + 8657557 = 8657798
337 + 8657461 = 8657798
349 + 8657449 = 8657798
367 + 8657431 = 8657798
421 + 8657377 = 8657798

Showing the first eight; more decompositions exist.
