Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8720046, here are decompositions:

19 + 8720027 = 8720046
47 + 8719999 = 8720046
59 + 8719987 = 8720046
103 + 8719943 = 8720046
107 + 8719939 = 8720046
173 + 8719873 = 8720046
199 + 8719847 = 8720046
227 + 8719819 = 8720046

Showing the first eight; more decompositions exist.
