Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 66284, here are decompositions:
- 13 + 66271 = 66284
- 181 + 66103 = 66284
- 433 + 65851 = 66284
- 457 + 65827 = 66284
- 523 + 65761 = 66284
- 571 + 65713 = 66284
- 577 + 65707 = 66284
- 607 + 65677 = 66284
Showing the first eight; more decompositions exist.
