Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8668440, here are decompositions:
- 17 + 8668423 = 8668440
- 19 + 8668421 = 8668440
- 37 + 8668403 = 8668440
- 59 + 8668381 = 8668440
- 61 + 8668379 = 8668440
- 71 + 8668369 = 8668440
- 73 + 8668367 = 8668440
- 83 + 8668357 = 8668440
Showing the first eight; more decompositions exist.
