Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8719212, here are decompositions:

13 + 8719199 = 8719212
53 + 8719159 = 8719212
71 + 8719141 = 8719212
79 + 8719133 = 8719212
113 + 8719099 = 8719212
163 + 8719049 = 8719212
181 + 8719031 = 8719212
191 + 8719021 = 8719212

Showing the first eight; more decompositions exist.
