Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31486234, here are decompositions:
- 5 + 31486229 = 31486234
- 71 + 31486163 = 31486234
- 113 + 31486121 = 31486234
- 281 + 31485953 = 31486234
- 293 + 31485941 = 31486234
- 317 + 31485917 = 31486234
- 401 + 31485833 = 31486234
- 431 + 31485803 = 31486234
Showing the first eight; more decompositions exist.
