Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8626242, here are decompositions:

5 + 8626237 = 8626242
13 + 8626229 = 8626242
61 + 8626181 = 8626242
73 + 8626169 = 8626242
83 + 8626159 = 8626242
101 + 8626141 = 8626242
103 + 8626139 = 8626242
113 + 8626129 = 8626242

Showing the first eight; more decompositions exist.
