Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8742192, here are decompositions:

5 + 8742187 = 8742192
23 + 8742169 = 8742192
31 + 8742161 = 8742192
59 + 8742133 = 8742192
71 + 8742121 = 8742192
89 + 8742103 = 8742192
181 + 8742011 = 8742192
241 + 8741951 = 8742192

Showing the first eight; more decompositions exist.
