Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8704420, here are decompositions:

3 + 8704417 = 8704420
17 + 8704403 = 8704420
89 + 8704331 = 8704420
107 + 8704313 = 8704420
167 + 8704253 = 8704420
191 + 8704229 = 8704420
227 + 8704193 = 8704420
251 + 8704169 = 8704420

Showing the first eight; more decompositions exist.
