Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 13972, here are decompositions:
- 5 + 13967 = 13972
- 41 + 13931 = 13972
- 59 + 13913 = 13972
- 71 + 13901 = 13972
- 89 + 13883 = 13972
- 113 + 13859 = 13972
- 131 + 13841 = 13972
- 173 + 13799 = 13972
Showing the first eight; more decompositions exist.
