Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31248, here are decompositions:
- 11 + 31237 = 31248
- 17 + 31231 = 31248
- 29 + 31219 = 31248
- 59 + 31189 = 31248
- 67 + 31181 = 31248
- 71 + 31177 = 31248
- 89 + 31159 = 31248
- 97 + 31151 = 31248
Showing the first eight; more decompositions exist.
