Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8742048, here are decompositions:

11 + 8742037 = 8742048
37 + 8742011 = 8742048
59 + 8741989 = 8742048
61 + 8741987 = 8742048
71 + 8741977 = 8742048
97 + 8741951 = 8742048
101 + 8741947 = 8742048
137 + 8741911 = 8742048

Showing the first eight; more decompositions exist.
