Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8627120, here are decompositions:

193 + 8626927 = 8627120
373 + 8626747 = 8627120
421 + 8626699 = 8627120
499 + 8626621 = 8627120
571 + 8626549 = 8627120
613 + 8626507 = 8627120
661 + 8626459 = 8627120
823 + 8626297 = 8627120

Showing the first eight; more decompositions exist.
