Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8624972, here are decompositions:

19 + 8624953 = 8624972
43 + 8624929 = 8624972
151 + 8624821 = 8624972
199 + 8624773 = 8624972
373 + 8624599 = 8624972
523 + 8624449 = 8624972
619 + 8624353 = 8624972
661 + 8624311 = 8624972

Showing the first eight; more decompositions exist.
