Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8667698, here are decompositions:

37 + 8667661 = 8667698
97 + 8667601 = 8667698
139 + 8667559 = 8667698
241 + 8667457 = 8667698
271 + 8667427 = 8667698
349 + 8667349 = 8667698
379 + 8667319 = 8667698
397 + 8667301 = 8667698

Showing the first eight; more decompositions exist.
