Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31527300, here are decompositions:
- 23 + 31527277 = 31527300
- 47 + 31527253 = 31527300
- 53 + 31527247 = 31527300
- 67 + 31527233 = 31527300
- 89 + 31527211 = 31527300
- 107 + 31527193 = 31527300
- 109 + 31527191 = 31527300
- 127 + 31527173 = 31527300
Showing the first eight; more decompositions exist.
