Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8742024, here are decompositions:

13 + 8742011 = 8742024
37 + 8741987 = 8742024
41 + 8741983 = 8742024
47 + 8741977 = 8742024
73 + 8741951 = 8742024
101 + 8741923 = 8742024
113 + 8741911 = 8742024
157 + 8741867 = 8742024

Showing the first eight; more decompositions exist.
