Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 12698, here are decompositions:

61 + 12637 = 12698
79 + 12619 = 12698
97 + 12601 = 12698
109 + 12589 = 12698
151 + 12547 = 12698
157 + 12541 = 12698
181 + 12517 = 12698
211 + 12487 = 12698

Showing the first eight; more decompositions exist.
