Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8721482, here are decompositions:

13 + 8721469 = 8721482
79 + 8721403 = 8721482
103 + 8721379 = 8721482
223 + 8721259 = 8721482
229 + 8721253 = 8721482
421 + 8721061 = 8721482
433 + 8721049 = 8721482
439 + 8721043 = 8721482

Showing the first eight; more decompositions exist.
