Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2090, here are decompositions:
- 3 + 2087 = 2090
- 7 + 2083 = 2090
- 37 + 2053 = 2090
- 61 + 2029 = 2090
- 73 + 2017 = 2090
- 79 + 2011 = 2090
- 97 + 1993 = 2090
- 103 + 1987 = 2090
Showing the first eight; more decompositions exist.
