Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8743478, here are decompositions:

19 + 8743459 = 8743478
31 + 8743447 = 8743478
61 + 8743417 = 8743478
67 + 8743411 = 8743478
151 + 8743327 = 8743478
199 + 8743279 = 8743478
379 + 8743099 = 8743478
547 + 8742931 = 8743478

Showing the first eight; more decompositions exist.
