Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2102, here are decompositions:
- 3 + 2099 = 2102
- 13 + 2089 = 2102
- 19 + 2083 = 2102
- 73 + 2029 = 2102
- 103 + 1999 = 2102
- 109 + 1993 = 2102
- 151 + 1951 = 2102
- 223 + 1879 = 2102
Showing the first eight; more decompositions exist.
