Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31527262, here are decompositions:
- 29 + 31527233 = 31527262
- 71 + 31527191 = 31527262
- 89 + 31527173 = 31527262
- 113 + 31527149 = 31527262
- 131 + 31527131 = 31527262
- 251 + 31527011 = 31527262
- 359 + 31526903 = 31527262
- 383 + 31526879 = 31527262
Showing the first eight; more decompositions exist.
