Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8727742, here are decompositions:

11 + 8727731 = 8727742
41 + 8727701 = 8727742
53 + 8727689 = 8727742
83 + 8727659 = 8727742
131 + 8727611 = 8727742
173 + 8727569 = 8727742
311 + 8727431 = 8727742
383 + 8727359 = 8727742

Showing the first eight; more decompositions exist.
