Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 126558, here are decompositions:
- 7 + 126551 = 126558
- 11 + 126547 = 126558
- 17 + 126541 = 126558
- 41 + 126517 = 126558
- 59 + 126499 = 126558
- 67 + 126491 = 126558
- 71 + 126487 = 126558
- 97 + 126461 = 126558
Showing the first eight; more decompositions exist.
