Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8743142, here are decompositions:

3 + 8743139 = 8743142
43 + 8743099 = 8743142
211 + 8742931 = 8743142
223 + 8742919 = 8743142
571 + 8742571 = 8743142
601 + 8742541 = 8743142
613 + 8742529 = 8743142
631 + 8742511 = 8743142

Showing the first eight; more decompositions exist.
