Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8642510, here are decompositions:

3 + 8642507 = 8642510
43 + 8642467 = 8642510
61 + 8642449 = 8642510
127 + 8642383 = 8642510
181 + 8642329 = 8642510
229 + 8642281 = 8642510
313 + 8642197 = 8642510
337 + 8642173 = 8642510

Showing the first eight; more decompositions exist.
