Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8642630, here are decompositions:

97 + 8642533 = 8642630
163 + 8642467 = 8642630
181 + 8642449 = 8642630
349 + 8642281 = 8642630
433 + 8642197 = 8642630
457 + 8642173 = 8642630
523 + 8642107 = 8642630
571 + 8642059 = 8642630

Showing the first eight; more decompositions exist.
