Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8699218, here are decompositions:

149 + 8699069 = 8699218
167 + 8699051 = 8699218
179 + 8699039 = 8699218
257 + 8698961 = 8699218
347 + 8698871 = 8699218
431 + 8698787 = 8699218
461 + 8698757 = 8699218
491 + 8698727 = 8699218

Showing the first eight; more decompositions exist.
