Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8625426, here are decompositions:

67 + 8625359 = 8625426
83 + 8625343 = 8625426
109 + 8625317 = 8625426
113 + 8625313 = 8625426
137 + 8625289 = 8625426
163 + 8625263 = 8625426
179 + 8625247 = 8625426
193 + 8625233 = 8625426

Showing the first eight; more decompositions exist.
