Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8662542, here are decompositions:

11 + 8662531 = 8662542
59 + 8662483 = 8662542
61 + 8662481 = 8662542
71 + 8662471 = 8662542
89 + 8662453 = 8662542
101 + 8662441 = 8662542
131 + 8662411 = 8662542
193 + 8662349 = 8662542

Showing the first eight; more decompositions exist.
