Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8642604, here are decompositions:

13 + 8642591 = 8642604
23 + 8642581 = 8642604
37 + 8642567 = 8642604
71 + 8642533 = 8642604
97 + 8642507 = 8642604
137 + 8642467 = 8642604
151 + 8642453 = 8642604
367 + 8642237 = 8642604

Showing the first eight; more decompositions exist.
