Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8747420, here are decompositions:

13 + 8747407 = 8747420
163 + 8747257 = 8747420
229 + 8747191 = 8747420
337 + 8747083 = 8747420
349 + 8747071 = 8747420
379 + 8747041 = 8747420
421 + 8746999 = 8747420
457 + 8746963 = 8747420

Showing the first eight; more decompositions exist.
