Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8720196, here are decompositions:

5 + 8720191 = 8720196
7 + 8720189 = 8720196
19 + 8720177 = 8720196
59 + 8720137 = 8720196
83 + 8720113 = 8720196
109 + 8720087 = 8720196
139 + 8720057 = 8720196
197 + 8719999 = 8720196

Showing the first eight; more decompositions exist.
