Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8614420, here are decompositions:

11 + 8614409 = 8614420
83 + 8614337 = 8614420
107 + 8614313 = 8614420
167 + 8614253 = 8614420
239 + 8614181 = 8614420
263 + 8614157 = 8614420
293 + 8614127 = 8614420
389 + 8614031 = 8614420

Showing the first eight; more decompositions exist.
