Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31527252, here are decompositions:
- 5 + 31527247 = 31527252
- 19 + 31527233 = 31527252
- 41 + 31527211 = 31527252
- 59 + 31527193 = 31527252
- 61 + 31527191 = 31527252
- 79 + 31527173 = 31527252
- 101 + 31527151 = 31527252
- 103 + 31527149 = 31527252
Showing the first eight; more decompositions exist.
