Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8747456, here are decompositions:

37 + 8747419 = 8747456
127 + 8747329 = 8747456
199 + 8747257 = 8747456
337 + 8747119 = 8747456
373 + 8747083 = 8747456
457 + 8746999 = 8747456
499 + 8746957 = 8747456
577 + 8746879 = 8747456

Showing the first eight; more decompositions exist.
