Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 100698, here are decompositions:

5 + 100693 = 100698
29 + 100669 = 100698
89 + 100609 = 100698
107 + 100591 = 100698
139 + 100559 = 100698
149 + 100549 = 100698
151 + 100547 = 100698
179 + 100519 = 100698

Showing the first eight; more decompositions exist.
