Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 11420, here are decompositions:
- 37 + 11383 = 11420
- 67 + 11353 = 11420
- 103 + 11317 = 11420
- 109 + 11311 = 11420
- 163 + 11257 = 11420
- 181 + 11239 = 11420
- 223 + 11197 = 11420
- 271 + 11149 = 11420
Showing the first eight; more decompositions exist.
