Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8618542, here are decompositions:

41 + 8618501 = 8618542
59 + 8618483 = 8618542
113 + 8618429 = 8618542
269 + 8618273 = 8618542
479 + 8618063 = 8618542
509 + 8618033 = 8618542
521 + 8618021 = 8618542
593 + 8617949 = 8618542

Showing the first eight; more decompositions exist.
