Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8641422, here are decompositions:
- 61 + 8641361 = 8641422
- 71 + 8641351 = 8641422
- 73 + 8641349 = 8641422
- 103 + 8641319 = 8641422
- 113 + 8641309 = 8641422
- 149 + 8641273 = 8641422
- 173 + 8641249 = 8641422
- 191 + 8641231 = 8641422
Showing the first eight; more decompositions exist.
