Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31526012, here are decompositions:
- 31 + 31525981 = 31526012
- 61 + 31525951 = 31526012
- 103 + 31525909 = 31526012
- 109 + 31525903 = 31526012
- 163 + 31525849 = 31526012
- 229 + 31525783 = 31526012
- 241 + 31525771 = 31526012
- 313 + 31525699 = 31526012
Showing the first eight; more decompositions exist.
