Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8740736, here are decompositions:

79 + 8740657 = 8740736
157 + 8740579 = 8740736
283 + 8740453 = 8740736
307 + 8740429 = 8740736
349 + 8740387 = 8740736
409 + 8740327 = 8740736
463 + 8740273 = 8740736
607 + 8740129 = 8740736

Showing the first eight; more decompositions exist.
