Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8716420, here are decompositions:

47 + 8716373 = 8716420
131 + 8716289 = 8716420
137 + 8716283 = 8716420
149 + 8716271 = 8716420
233 + 8716187 = 8716420
239 + 8716181 = 8716420
257 + 8716163 = 8716420
269 + 8716151 = 8716420

Showing the first eight; more decompositions exist.
