Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8743018, here are decompositions:

17 + 8743001 = 8743018
41 + 8742977 = 8743018
101 + 8742917 = 8743018
131 + 8742887 = 8743018
197 + 8742821 = 8743018
239 + 8742779 = 8743018
467 + 8742551 = 8743018
521 + 8742497 = 8743018

Showing the first eight; more decompositions exist.
