Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8742260, here are decompositions:

67 + 8742193 = 8742260
73 + 8742187 = 8742260
103 + 8742157 = 8742260
127 + 8742133 = 8742260
139 + 8742121 = 8742260
157 + 8742103 = 8742260
193 + 8742067 = 8742260
223 + 8742037 = 8742260

Showing the first eight; more decompositions exist.
