Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8680212, here are decompositions:

11 + 8680201 = 8680212
41 + 8680171 = 8680212
59 + 8680153 = 8680212
109 + 8680103 = 8680212
113 + 8680099 = 8680212
139 + 8680073 = 8680212
179 + 8680033 = 8680212
239 + 8679973 = 8680212

Showing the first eight; more decompositions exist.
