Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8742588, here are decompositions:

11 + 8742577 = 8742588
17 + 8742571 = 8742588
37 + 8742551 = 8742588
47 + 8742541 = 8742588
59 + 8742529 = 8742588
89 + 8742499 = 8742588
139 + 8742449 = 8742588
167 + 8742421 = 8742588

Showing the first eight; more decompositions exist.
