Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8699478, here are decompositions:

59 + 8699419 = 8699478
89 + 8699389 = 8699478
97 + 8699381 = 8699478
127 + 8699351 = 8699478
167 + 8699311 = 8699478
181 + 8699297 = 8699478
199 + 8699279 = 8699478
239 + 8699239 = 8699478

Showing the first eight; more decompositions exist.
