Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8742144, here are decompositions:

11 + 8742133 = 8742144
23 + 8742121 = 8742144
41 + 8742103 = 8742144
67 + 8742077 = 8742144
107 + 8742037 = 8742144
157 + 8741987 = 8742144
167 + 8741977 = 8742144
193 + 8741951 = 8742144

Showing the first eight; more decompositions exist.
