Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8747378, here are decompositions:

127 + 8747251 = 8747378
307 + 8747071 = 8747378
337 + 8747041 = 8747378
379 + 8746999 = 8747378
421 + 8746957 = 8747378
439 + 8746939 = 8747378
457 + 8746921 = 8747378
499 + 8746879 = 8747378

Showing the first eight; more decompositions exist.
