Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8747498, here are decompositions:

79 + 8747419 = 8747498
241 + 8747257 = 8747498
307 + 8747191 = 8747498
379 + 8747119 = 8747498
457 + 8747041 = 8747498
499 + 8746999 = 8747498
541 + 8746957 = 8747498
577 + 8746921 = 8747498

Showing the first eight; more decompositions exist.
