Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8660542, here are decompositions:

3 + 8660539 = 8660542
5 + 8660537 = 8660542
173 + 8660369 = 8660542
251 + 8660291 = 8660542
353 + 8660189 = 8660542
461 + 8660081 = 8660542
491 + 8660051 = 8660542
503 + 8660039 = 8660542

Showing the first eight; more decompositions exist.
