Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8624290, here are decompositions:

23 + 8624267 = 8624290
41 + 8624249 = 8624290
47 + 8624243 = 8624290
53 + 8624237 = 8624290
89 + 8624201 = 8624290
107 + 8624183 = 8624290
113 + 8624177 = 8624290
131 + 8624159 = 8624290

Showing the first eight; more decompositions exist.
