Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31302, here are decompositions:
- 31 + 31271 = 31302
- 43 + 31259 = 31302
- 53 + 31249 = 31302
- 71 + 31231 = 31302
- 79 + 31223 = 31302
- 83 + 31219 = 31302
- 109 + 31193 = 31302
- 113 + 31189 = 31302
Showing the first eight; more decompositions exist.
