Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 85972, here are decompositions:
- 41 + 85931 = 85972
- 83 + 85889 = 85972
- 179 + 85793 = 85972
- 191 + 85781 = 85972
- 239 + 85733 = 85972
- 269 + 85703 = 85972
- 281 + 85691 = 85972
- 311 + 85661 = 85972
Showing the first eight; more decompositions exist.
