Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 66830, here are decompositions:
- 67 + 66763 = 66830
- 79 + 66751 = 66830
- 97 + 66733 = 66830
- 109 + 66721 = 66830
- 229 + 66601 = 66830
- 277 + 66553 = 66830
- 307 + 66523 = 66830
- 331 + 66499 = 66830
Showing the first eight; more decompositions exist.
