Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8601666, here are decompositions:
- 13 + 8601653 = 8601666
- 19 + 8601647 = 8601666
- 37 + 8601629 = 8601666
- 79 + 8601587 = 8601666
- 97 + 8601569 = 8601666
- 109 + 8601557 = 8601666
- 163 + 8601503 = 8601666
- 167 + 8601499 = 8601666
Showing the first eight; more decompositions exist.
