Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 68426, here are decompositions:
- 37 + 68389 = 68426
- 97 + 68329 = 68426
- 199 + 68227 = 68426
- 313 + 68113 = 68426
- 367 + 68059 = 68426
- 373 + 68053 = 68426
- 433 + 67993 = 68426
- 439 + 67987 = 68426
Showing the first eight; more decompositions exist.
