Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8681956, here are decompositions:

167 + 8681789 = 8681956
263 + 8681693 = 8681956
293 + 8681663 = 8681956
317 + 8681639 = 8681956
389 + 8681567 = 8681956
443 + 8681513 = 8681956
449 + 8681507 = 8681956
467 + 8681489 = 8681956

Showing the first eight; more decompositions exist.
