Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8620120, here are decompositions:

11 + 8620109 = 8620120
71 + 8620049 = 8620120
227 + 8619893 = 8620120
251 + 8619869 = 8620120
263 + 8619857 = 8620120
347 + 8619773 = 8620120
401 + 8619719 = 8620120
569 + 8619551 = 8620120

Showing the first eight; more decompositions exist.
