Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8662458, here are decompositions:

5 + 8662453 = 8662458
11 + 8662447 = 8662458
17 + 8662441 = 8662458
47 + 8662411 = 8662458
61 + 8662397 = 8662458
109 + 8662349 = 8662458
131 + 8662327 = 8662458
139 + 8662319 = 8662458

Showing the first eight; more decompositions exist.
