Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 86830, here are decompositions:
- 17 + 86813 = 86830
- 47 + 86783 = 86830
- 59 + 86771 = 86830
- 101 + 86729 = 86830
- 137 + 86693 = 86830
- 251 + 86579 = 86830
- 257 + 86573 = 86830
- 269 + 86561 = 86830
Showing the first eight; more decompositions exist.
