Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8662558, here are decompositions:

5 + 8662553 = 8662558
17 + 8662541 = 8662558
41 + 8662517 = 8662558
71 + 8662487 = 8662558
239 + 8662319 = 8662558
389 + 8662169 = 8662558
431 + 8662127 = 8662558
449 + 8662109 = 8662558

Showing the first eight; more decompositions exist.
