Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8742108, here are decompositions:

5 + 8742103 = 8742108
31 + 8742077 = 8742108
41 + 8742067 = 8742108
71 + 8742037 = 8742108
97 + 8742011 = 8742108
131 + 8741977 = 8742108
157 + 8741951 = 8742108
197 + 8741911 = 8742108

Showing the first eight; more decompositions exist.
