Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2698, here are decompositions:

5 + 2693 = 2698
11 + 2687 = 2698
41 + 2657 = 2698
89 + 2609 = 2698
107 + 2591 = 2698
149 + 2549 = 2698
167 + 2531 = 2698
239 + 2459 = 2698

Showing the first eight; more decompositions exist.
