Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 151698, here are decompositions:

5 + 151693 = 151698
11 + 151687 = 151698
17 + 151681 = 151698
31 + 151667 = 151698
47 + 151651 = 151698
61 + 151637 = 151698
67 + 151631 = 151698
89 + 151609 = 151698

Showing the first eight; more decompositions exist.
