Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2072, here are decompositions:
- 3 + 2069 = 2072
- 19 + 2053 = 2072
- 43 + 2029 = 2072
- 61 + 2011 = 2072
- 73 + 1999 = 2072
- 79 + 1993 = 2072
- 139 + 1933 = 2072
- 193 + 1879 = 2072
Showing the first eight; more decompositions exist.
