Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8742018, here are decompositions:

7 + 8742011 = 8742018
29 + 8741989 = 8742018
31 + 8741987 = 8742018
41 + 8741977 = 8742018
67 + 8741951 = 8742018
71 + 8741947 = 8742018
107 + 8741911 = 8742018
151 + 8741867 = 8742018

Showing the first eight; more decompositions exist.
