Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8742746, here are decompositions:

7 + 8742739 = 8742746
73 + 8742673 = 8742746
109 + 8742637 = 8742746
277 + 8742469 = 8742746
283 + 8742463 = 8742746
367 + 8742379 = 8742746
379 + 8742367 = 8742746
433 + 8742313 = 8742746

Showing the first eight; more decompositions exist.
