Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 27638, here are decompositions:
- 7 + 27631 = 27638
- 97 + 27541 = 27638
- 109 + 27529 = 27638
- 151 + 27487 = 27638
- 157 + 27481 = 27638
- 181 + 27457 = 27638
- 211 + 27427 = 27638
- 229 + 27409 = 27638
Showing the first eight; more decompositions exist.
