Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 6558, here are decompositions:
- 5 + 6553 = 6558
- 7 + 6551 = 6558
- 11 + 6547 = 6558
- 29 + 6529 = 6558
- 37 + 6521 = 6558
- 67 + 6491 = 6558
- 89 + 6469 = 6558
- 107 + 6451 = 6558
Showing the first eight; more decompositions exist.
