Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8747540, here are decompositions:

13 + 8747527 = 8747540
211 + 8747329 = 8747540
283 + 8747257 = 8747540
349 + 8747191 = 8747540
421 + 8747119 = 8747540
457 + 8747083 = 8747540
499 + 8747041 = 8747540
541 + 8746999 = 8747540

Showing the first eight; more decompositions exist.
