Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8742558, here are decompositions:

7 + 8742551 = 8742558
17 + 8742541 = 8742558
29 + 8742529 = 8742558
47 + 8742511 = 8742558
59 + 8742499 = 8742558
61 + 8742497 = 8742558
89 + 8742469 = 8742558
109 + 8742449 = 8742558

Showing the first eight; more decompositions exist.
