Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8668422, here are decompositions:
- 19 + 8668403 = 8668422
- 41 + 8668381 = 8668422
- 43 + 8668379 = 8668422
- 53 + 8668369 = 8668422
- 73 + 8668349 = 8668422
- 149 + 8668273 = 8668422
- 229 + 8668193 = 8668422
- 271 + 8668151 = 8668422
Showing the first eight; more decompositions exist.
