Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 981698, here are decompositions:

7 + 981691 = 981698
61 + 981637 = 981698
97 + 981601 = 981698
181 + 981517 = 981698
307 + 981391 = 981698
379 + 981319 = 981698
397 + 981301 = 981698
409 + 981289 = 981698

Showing the first eight; more decompositions exist.
