Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8642658, here are decompositions:

7 + 8642651 = 8642658
67 + 8642591 = 8642658
139 + 8642519 = 8642658
149 + 8642509 = 8642658
151 + 8642507 = 8642658
191 + 8642467 = 8642658
229 + 8642429 = 8642658
421 + 8642237 = 8642658

Showing the first eight; more decompositions exist.
