Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 90830, here are decompositions:
- 7 + 90823 = 90830
- 37 + 90793 = 90830
- 43 + 90787 = 90830
- 127 + 90703 = 90830
- 151 + 90679 = 90830
- 199 + 90631 = 90830
- 211 + 90619 = 90830
- 283 + 90547 = 90830
Showing the first eight; more decompositions exist.
