Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 11426, here are decompositions:
- 3 + 11423 = 11426
- 43 + 11383 = 11426
- 73 + 11353 = 11426
- 97 + 11329 = 11426
- 109 + 11317 = 11426
- 127 + 11299 = 11426
- 139 + 11287 = 11426
- 229 + 11197 = 11426
Showing the first eight; more decompositions exist.
