Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8743042, here are decompositions:

5 + 8743037 = 8743042
23 + 8743019 = 8743042
41 + 8743001 = 8743042
101 + 8742941 = 8743042
263 + 8742779 = 8743042
353 + 8742689 = 8743042
389 + 8742653 = 8743042
419 + 8742623 = 8743042

Showing the first eight; more decompositions exist.
