Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8720468, here are decompositions:

37 + 8720431 = 8720468
61 + 8720407 = 8720468
79 + 8720389 = 8720468
151 + 8720317 = 8720468
157 + 8720311 = 8720468
241 + 8720227 = 8720468
277 + 8720191 = 8720468
307 + 8720161 = 8720468

Showing the first eight; more decompositions exist.
