Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8642522, here are decompositions:

3 + 8642519 = 8642522
13 + 8642509 = 8642522
73 + 8642449 = 8642522
139 + 8642383 = 8642522
193 + 8642329 = 8642522
241 + 8642281 = 8642522
349 + 8642173 = 8642522
463 + 8642059 = 8642522

Showing the first eight; more decompositions exist.
