Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8716438, here are decompositions:

149 + 8716289 = 8716438
167 + 8716271 = 8716438
251 + 8716187 = 8716438
257 + 8716181 = 8716438
431 + 8716007 = 8716438
449 + 8715989 = 8716438
461 + 8715977 = 8716438
491 + 8715947 = 8716438

Showing the first eight; more decompositions exist.
