Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 19090, here are decompositions:
- 3 + 19087 = 19090
- 11 + 19079 = 19090
- 17 + 19073 = 19090
- 53 + 19037 = 19090
- 59 + 19031 = 19090
- 89 + 19001 = 19090
- 131 + 18959 = 19090
- 173 + 18917 = 19090
Showing the first eight; more decompositions exist.
