Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8720110, here are decompositions:

23 + 8720087 = 8720110
29 + 8720081 = 8720110
53 + 8720057 = 8720110
83 + 8720027 = 8720110
149 + 8719961 = 8720110
167 + 8719943 = 8720110
263 + 8719847 = 8720110
293 + 8719817 = 8720110

Showing the first eight; more decompositions exist.
