Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8742542, here are decompositions:

13 + 8742529 = 8742542
31 + 8742511 = 8742542
43 + 8742499 = 8742542
73 + 8742469 = 8742542
79 + 8742463 = 8742542
163 + 8742379 = 8742542
229 + 8742313 = 8742542
283 + 8742259 = 8742542

Showing the first eight; more decompositions exist.
