Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8720214, here are decompositions:

23 + 8720191 = 8720214
37 + 8720177 = 8720214
43 + 8720171 = 8720214
53 + 8720161 = 8720214
101 + 8720113 = 8720214
103 + 8720111 = 8720214
127 + 8720087 = 8720214
157 + 8720057 = 8720214

Showing the first eight; more decompositions exist.
