Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31028, here are decompositions:
- 79 + 30949 = 31028
- 97 + 30931 = 31028
- 157 + 30871 = 31028
- 199 + 30829 = 31028
- 211 + 30817 = 31028
- 271 + 30757 = 31028
- 331 + 30697 = 31028
- 367 + 30661 = 31028
Showing the first eight; more decompositions exist.
