Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 27998, here are decompositions:

31 + 27967 = 27998
37 + 27961 = 27998
79 + 27919 = 27998
97 + 27901 = 27998
151 + 27847 = 27998
181 + 27817 = 27998
199 + 27799 = 27998
307 + 27691 = 27998

Showing the first eight; more decompositions exist.
