Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 81314, here are decompositions:
- 7 + 81307 = 81314
- 31 + 81283 = 81314
- 151 + 81163 = 81314
- 157 + 81157 = 81314
- 271 + 81043 = 81314
- 283 + 81031 = 81314
- 313 + 81001 = 81314
- 397 + 80917 = 81314
Showing the first eight; more decompositions exist.
