Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8747480, here are decompositions:

61 + 8747419 = 8747480
73 + 8747407 = 8747480
151 + 8747329 = 8747480
223 + 8747257 = 8747480
229 + 8747251 = 8747480
397 + 8747083 = 8747480
409 + 8747071 = 8747480
439 + 8747041 = 8747480

Showing the first eight; more decompositions exist.
