Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8720116, here are decompositions:

3 + 8720113 = 8720116
5 + 8720111 = 8720116
29 + 8720087 = 8720116
59 + 8720057 = 8720116
89 + 8720027 = 8720116
173 + 8719943 = 8720116
269 + 8719847 = 8720116
809 + 8719307 = 8720116

Showing the first eight; more decompositions exist.
