Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8699686, here are decompositions:

53 + 8699633 = 8699686
113 + 8699573 = 8699686
167 + 8699519 = 8699686
173 + 8699513 = 8699686
197 + 8699489 = 8699686
263 + 8699423 = 8699686
389 + 8699297 = 8699686
449 + 8699237 = 8699686

Showing the first eight; more decompositions exist.
