Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 85880, here are decompositions:
- 37 + 85843 = 85880
- 43 + 85837 = 85880
- 61 + 85819 = 85880
- 163 + 85717 = 85880
- 211 + 85669 = 85880
- 241 + 85639 = 85880
- 283 + 85597 = 85880
- 331 + 85549 = 85880
Showing the first eight; more decompositions exist.
