Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1001698, here are decompositions:

11 + 1001687 = 1001698
29 + 1001669 = 1001698
59 + 1001639 = 1001698
149 + 1001549 = 1001698
167 + 1001531 = 1001698
197 + 1001501 = 1001698
239 + 1001459 = 1001698
251 + 1001447 = 1001698

Showing the first eight; more decompositions exist.
