Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 27860, here are decompositions:
- 13 + 27847 = 27860
- 37 + 27823 = 27860
- 43 + 27817 = 27860
- 61 + 27799 = 27860
- 67 + 27793 = 27860
- 97 + 27763 = 27860
- 109 + 27751 = 27860
- 127 + 27733 = 27860
Showing the first eight; more decompositions exist.
