Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8756220, here are decompositions:

7 + 8756213 = 8756220
17 + 8756203 = 8756220
19 + 8756201 = 8756220
61 + 8756159 = 8756220
71 + 8756149 = 8756220
101 + 8756119 = 8756220
103 + 8756117 = 8756220
107 + 8756113 = 8756220

Showing the first eight; more decompositions exist.
