Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 27908, here are decompositions:
- 7 + 27901 = 27908
- 61 + 27847 = 27908
- 109 + 27799 = 27908
- 157 + 27751 = 27908
- 211 + 27697 = 27908
- 277 + 27631 = 27908
- 367 + 27541 = 27908
- 379 + 27529 = 27908
Showing the first eight; more decompositions exist.
