Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8720050, here are decompositions:

23 + 8720027 = 8720050
89 + 8719961 = 8720050
107 + 8719943 = 8720050
233 + 8719817 = 8720050
347 + 8719703 = 8720050
389 + 8719661 = 8720050
509 + 8719541 = 8720050
659 + 8719391 = 8720050

Showing the first eight; more decompositions exist.
