Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8742512, here are decompositions:

13 + 8742499 = 8742512
19 + 8742493 = 8742512
43 + 8742469 = 8742512
199 + 8742313 = 8742512
379 + 8742133 = 8742512
409 + 8742103 = 8742512
523 + 8741989 = 8742512
601 + 8741911 = 8742512

Showing the first eight; more decompositions exist.
