Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8722698, here are decompositions:

37 + 8722661 = 8722698
67 + 8722631 = 8722698
157 + 8722541 = 8722698
181 + 8722517 = 8722698
199 + 8722499 = 8722698
227 + 8722471 = 8722698
239 + 8722459 = 8722698
251 + 8722447 = 8722698

Showing the first eight; more decompositions exist.
