Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8626142, here are decompositions:

3 + 8626139 = 8626142
13 + 8626129 = 8626142
43 + 8626099 = 8626142
79 + 8626063 = 8626142
163 + 8625979 = 8626142
181 + 8625961 = 8626142
229 + 8625913 = 8626142
241 + 8625901 = 8626142

Showing the first eight; more decompositions exist.
