Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8742150, here are decompositions:

17 + 8742133 = 8742150
29 + 8742121 = 8742150
47 + 8742103 = 8742150
73 + 8742077 = 8742150
83 + 8742067 = 8742150
113 + 8742037 = 8742150
139 + 8742011 = 8742150
163 + 8741987 = 8742150

Showing the first eight; more decompositions exist.
