Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8742648, here are decompositions:

11 + 8742637 = 8742648
71 + 8742577 = 8742648
97 + 8742551 = 8742648
107 + 8742541 = 8742648
137 + 8742511 = 8742648
149 + 8742499 = 8742648
151 + 8742497 = 8742648
179 + 8742469 = 8742648

Showing the first eight; more decompositions exist.
