Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31527276, here are decompositions:
- 23 + 31527253 = 31527276
- 29 + 31527247 = 31527276
- 43 + 31527233 = 31527276
- 83 + 31527193 = 31527276
- 103 + 31527173 = 31527276
- 127 + 31527149 = 31527276
- 167 + 31527109 = 31527276
- 199 + 31527077 = 31527276
Showing the first eight; more decompositions exist.
