Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8681998, here are decompositions:

29 + 8681969 = 8681998
41 + 8681957 = 8681998
167 + 8681831 = 8681998
359 + 8681639 = 8681998
419 + 8681579 = 8681998
431 + 8681567 = 8681998
449 + 8681549 = 8681998
491 + 8681507 = 8681998

Showing the first eight; more decompositions exist.
