Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31200, here are decompositions:
- 7 + 31193 = 31200
- 11 + 31189 = 31200
- 17 + 31183 = 31200
- 19 + 31181 = 31200
- 23 + 31177 = 31200
- 41 + 31159 = 31200
- 47 + 31153 = 31200
- 53 + 31147 = 31200
Showing the first eight; more decompositions exist.
