Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 77090, here are decompositions:
- 43 + 77047 = 77090
- 61 + 77029 = 77090
- 67 + 77023 = 77090
- 73 + 77017 = 77090
- 127 + 76963 = 77090
- 271 + 76819 = 77090
- 313 + 76777 = 77090
- 337 + 76753 = 77090
Showing the first eight; more decompositions exist.
