Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8720480, here are decompositions:

3 + 8720477 = 8720480
73 + 8720407 = 8720480
163 + 8720317 = 8720480
199 + 8720281 = 8720480
367 + 8720113 = 8720480
409 + 8720071 = 8720480
541 + 8719939 = 8720480
577 + 8719903 = 8720480

Showing the first eight; more decompositions exist.
