Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31544300, here are decompositions:
- 3 + 31544297 = 31544300
- 19 + 31544281 = 31544300
- 79 + 31544221 = 31544300
- 211 + 31544089 = 31544300
- 223 + 31544077 = 31544300
- 313 + 31543987 = 31544300
- 373 + 31543927 = 31544300
- 397 + 31543903 = 31544300
Showing the first eight; more decompositions exist.
