Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8747320, here are decompositions:

47 + 8747273 = 8747320
59 + 8747261 = 8747320
107 + 8747213 = 8747320
149 + 8747171 = 8747320
227 + 8747093 = 8747320
353 + 8746967 = 8747320
383 + 8746937 = 8747320
401 + 8746919 = 8747320

Showing the first eight; more decompositions exist.
