Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8724624, here are decompositions:

5 + 8724619 = 8724624
23 + 8724601 = 8724624
113 + 8724511 = 8724624
127 + 8724497 = 8724624
131 + 8724493 = 8724624
137 + 8724487 = 8724624
157 + 8724467 = 8724624
163 + 8724461 = 8724624

Showing the first eight; more decompositions exist.
