Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8720548, here are decompositions:

17 + 8720531 = 8720548
59 + 8720489 = 8720548
71 + 8720477 = 8720548
101 + 8720447 = 8720548
131 + 8720417 = 8720548
227 + 8720321 = 8720548
359 + 8720189 = 8720548
461 + 8720087 = 8720548

Showing the first eight; more decompositions exist.
