Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31527850, here are decompositions:
- 23 + 31527827 = 31527850
- 149 + 31527701 = 31527850
- 173 + 31527677 = 31527850
- 191 + 31527659 = 31527850
- 281 + 31527569 = 31527850
- 317 + 31527533 = 31527850
- 353 + 31527497 = 31527850
- 359 + 31527491 = 31527850
Showing the first eight; more decompositions exist.
