Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 28076, here are decompositions:
- 7 + 28069 = 28076
- 19 + 28057 = 28076
- 79 + 27997 = 28076
- 109 + 27967 = 28076
- 157 + 27919 = 28076
- 193 + 27883 = 28076
- 229 + 27847 = 28076
- 277 + 27799 = 28076
Showing the first eight; more decompositions exist.
