Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 85664, here are decompositions:
- 3 + 85661 = 85664
- 37 + 85627 = 85664
- 43 + 85621 = 85664
- 67 + 85597 = 85664
- 151 + 85513 = 85664
- 211 + 85453 = 85664
- 283 + 85381 = 85664
- 331 + 85333 = 85664
Showing the first eight; more decompositions exist.
