Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31526992, here are decompositions:
- 53 + 31526939 = 31526992
- 71 + 31526921 = 31526992
- 89 + 31526903 = 31526992
- 113 + 31526879 = 31526992
- 173 + 31526819 = 31526992
- 239 + 31526753 = 31526992
- 269 + 31526723 = 31526992
- 359 + 31526633 = 31526992
Showing the first eight; more decompositions exist.
