Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8642706, here are decompositions:

73 + 8642633 = 8642706
139 + 8642567 = 8642706
173 + 8642533 = 8642706
197 + 8642509 = 8642706
199 + 8642507 = 8642706
239 + 8642467 = 8642706
257 + 8642449 = 8642706
277 + 8642429 = 8642706

Showing the first eight; more decompositions exist.
