Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 121698, here are decompositions:

11 + 121687 = 121698
37 + 121661 = 121698
61 + 121637 = 121698
67 + 121631 = 121698
89 + 121609 = 121698
107 + 121591 = 121698
127 + 121571 = 121698
139 + 121559 = 121698

Showing the first eight; more decompositions exist.
