Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8667722, here are decompositions:

61 + 8667661 = 8667722
109 + 8667613 = 8667722
163 + 8667559 = 8667722
211 + 8667511 = 8667722
373 + 8667349 = 8667722
409 + 8667313 = 8667722
421 + 8667301 = 8667722
433 + 8667289 = 8667722

Showing the first eight; more decompositions exist.
