Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 90230, here are decompositions:
- 3 + 90227 = 90230
- 13 + 90217 = 90230
- 31 + 90199 = 90230
- 43 + 90187 = 90230
- 67 + 90163 = 90230
- 103 + 90127 = 90230
- 109 + 90121 = 90230
- 157 + 90073 = 90230
Showing the first eight; more decompositions exist.
