Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8624440, here are decompositions:
- 47 + 8624393 = 8624440
- 113 + 8624327 = 8624440
- 173 + 8624267 = 8624440
- 191 + 8624249 = 8624440
- 197 + 8624243 = 8624440
- 239 + 8624201 = 8624440
- 257 + 8624183 = 8624440
- 263 + 8624177 = 8624440
Showing the first eight; more decompositions exist.
