Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31238, here are decompositions:
- 7 + 31231 = 31238
- 19 + 31219 = 31238
- 61 + 31177 = 31238
- 79 + 31159 = 31238
- 157 + 31081 = 31238
- 199 + 31039 = 31238
- 307 + 30931 = 31238
- 367 + 30871 = 31238
Showing the first eight; more decompositions exist.
