Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 12240, here are decompositions:
- 13 + 12227 = 12240
- 29 + 12211 = 12240
- 37 + 12203 = 12240
- 43 + 12197 = 12240
- 79 + 12161 = 12240
- 83 + 12157 = 12240
- 97 + 12143 = 12240
- 127 + 12113 = 12240
Showing the first eight; more decompositions exist.
