Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8742536, here are decompositions:

7 + 8742529 = 8742536
37 + 8742499 = 8742536
43 + 8742493 = 8742536
67 + 8742469 = 8742536
73 + 8742463 = 8742536
157 + 8742379 = 8742536
223 + 8742313 = 8742536
277 + 8742259 = 8742536

Showing the first eight; more decompositions exist.
