Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8624672, here are decompositions:

3 + 8624669 = 8624672
73 + 8624599 = 8624672
223 + 8624449 = 8624672
349 + 8624323 = 8624672
421 + 8624251 = 8624672
541 + 8624131 = 8624672
571 + 8624101 = 8624672
613 + 8624059 = 8624672

Showing the first eight; more decompositions exist.
