Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8662538, here are decompositions:

7 + 8662531 = 8662538
67 + 8662471 = 8662538
97 + 8662441 = 8662538
127 + 8662411 = 8662538
211 + 8662327 = 8662538
337 + 8662201 = 8662538
349 + 8662189 = 8662538
541 + 8661997 = 8662538

Showing the first eight; more decompositions exist.
