Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8720554, here are decompositions:

23 + 8720531 = 8720554
41 + 8720513 = 8720554
71 + 8720483 = 8720554
83 + 8720471 = 8720554
107 + 8720447 = 8720554
137 + 8720417 = 8720554
233 + 8720321 = 8720554
383 + 8720171 = 8720554

Showing the first eight; more decompositions exist.
