Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 86788, here are decompositions:
- 5 + 86783 = 86788
- 17 + 86771 = 86788
- 59 + 86729 = 86788
- 227 + 86561 = 86788
- 257 + 86531 = 86788
- 311 + 86477 = 86788
- 347 + 86441 = 86788
- 389 + 86399 = 86788
Showing the first eight; more decompositions exist.
