Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8661364, here are decompositions:

11 + 8661353 = 8661364
53 + 8661311 = 8661364
83 + 8661281 = 8661364
113 + 8661251 = 8661364
167 + 8661197 = 8661364
191 + 8661173 = 8661364
227 + 8661137 = 8661364
317 + 8661047 = 8661364

Showing the first eight; more decompositions exist.
