Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8721294, here are decompositions:

13 + 8721281 = 8721294
41 + 8721253 = 8721294
97 + 8721197 = 8721294
103 + 8721191 = 8721294
137 + 8721157 = 8721294
173 + 8721121 = 8721294
193 + 8721101 = 8721294
233 + 8721061 = 8721294

Showing the first eight; more decompositions exist.
