Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31256, here are decompositions:
- 3 + 31253 = 31256
- 7 + 31249 = 31256
- 19 + 31237 = 31256
- 37 + 31219 = 31256
- 67 + 31189 = 31256
- 73 + 31183 = 31256
- 79 + 31177 = 31256
- 97 + 31159 = 31256
Showing the first eight; more decompositions exist.
