Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8720106, here are decompositions:

19 + 8720087 = 8720106
79 + 8720027 = 8720106
107 + 8719999 = 8720106
163 + 8719943 = 8720106
167 + 8719939 = 8720106
233 + 8719873 = 8720106
293 + 8719813 = 8720106
359 + 8719747 = 8720106

Showing the first eight; more decompositions exist.
