Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8720450, here are decompositions:

3 + 8720447 = 8720450
19 + 8720431 = 8720450
43 + 8720407 = 8720450
61 + 8720389 = 8720450
103 + 8720347 = 8720450
139 + 8720311 = 8720450
223 + 8720227 = 8720450
313 + 8720137 = 8720450

Showing the first eight; more decompositions exist.
