Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 20072, here are decompositions:
- 43 + 20029 = 20072
- 61 + 20011 = 20072
- 79 + 19993 = 20072
- 109 + 19963 = 20072
- 181 + 19891 = 20072
- 211 + 19861 = 20072
- 229 + 19843 = 20072
- 271 + 19801 = 20072
Showing the first eight; more decompositions exist.
