Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31544680, here are decompositions:
- 23 + 31544657 = 31544680
- 107 + 31544573 = 31544680
- 137 + 31544543 = 31544680
- 149 + 31544531 = 31544680
- 263 + 31544417 = 31544680
- 317 + 31544363 = 31544680
- 383 + 31544297 = 31544680
- 467 + 31544213 = 31544680
Showing the first eight; more decompositions exist.
