Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8642698, here are decompositions:

47 + 8642651 = 8642698
107 + 8642591 = 8642698
131 + 8642567 = 8642698
179 + 8642519 = 8642698
191 + 8642507 = 8642698
269 + 8642429 = 8642698
461 + 8642237 = 8642698
509 + 8642189 = 8642698

Showing the first eight; more decompositions exist.
