Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8742174, here are decompositions:

5 + 8742169 = 8742174
13 + 8742161 = 8742174
17 + 8742157 = 8742174
41 + 8742133 = 8742174
53 + 8742121 = 8742174
71 + 8742103 = 8742174
97 + 8742077 = 8742174
107 + 8742067 = 8742174

Showing the first eight; more decompositions exist.
