Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 27872, here are decompositions:
- 73 + 27799 = 27872
- 79 + 27793 = 27872
- 109 + 27763 = 27872
- 139 + 27733 = 27872
- 181 + 27691 = 27872
- 199 + 27673 = 27872
- 241 + 27631 = 27872
- 331 + 27541 = 27872
Showing the first eight; more decompositions exist.
