Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8643126, here are decompositions:
- 5 + 8643121 = 8643126
- 17 + 8643109 = 8643126
- 43 + 8643083 = 8643126
- 67 + 8643059 = 8643126
- 73 + 8643053 = 8643126
- 103 + 8643023 = 8643126
- 113 + 8643013 = 8643126
- 137 + 8642989 = 8643126
Showing the first eight; more decompositions exist.
