Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 29090, here are decompositions:
- 13 + 29077 = 29090
- 31 + 29059 = 29090
- 67 + 29023 = 29090
- 73 + 29017 = 29090
- 157 + 28933 = 29090
- 163 + 28927 = 29090
- 181 + 28909 = 29090
- 211 + 28879 = 29090
Showing the first eight; more decompositions exist.
