Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8742206, here are decompositions:

13 + 8742193 = 8742206
19 + 8742187 = 8742206
37 + 8742169 = 8742206
73 + 8742133 = 8742206
103 + 8742103 = 8742206
139 + 8742067 = 8742206
223 + 8741983 = 8742206
229 + 8741977 = 8742206

Showing the first eight; more decompositions exist.
