Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 12698, here are decompositions:
- 61 + 12637 = 12698
- 79 + 12619 = 12698
- 97 + 12601 = 12698
- 109 + 12589 = 12698
- 151 + 12547 = 12698
- 157 + 12541 = 12698
- 181 + 12517 = 12698
- 211 + 12487 = 12698
Showing the first eight; more decompositions exist.
