Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 23090, here are decompositions:
- 3 + 23087 = 23090
- 19 + 23071 = 23090
- 31 + 23059 = 23090
- 37 + 23053 = 23090
- 61 + 23029 = 23090
- 73 + 23017 = 23090
- 79 + 23011 = 23090
- 97 + 22993 = 23090
Showing the first eight; more decompositions exist.
