Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 66320, here are decompositions:
- 19 + 66301 = 66320
- 151 + 66169 = 66320
- 211 + 66109 = 66320
- 283 + 66037 = 66320
- 337 + 65983 = 66320
- 421 + 65899 = 66320
- 439 + 65881 = 66320
- 601 + 65719 = 66320
Showing the first eight; more decompositions exist.
