Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31544866, here are decompositions:
- 47 + 31544819 = 31544866
- 83 + 31544783 = 31544866
- 107 + 31544759 = 31544866
- 149 + 31544717 = 31544866
- 293 + 31544573 = 31544866
- 449 + 31544417 = 31544866
- 503 + 31544363 = 31544866
- 569 + 31544297 = 31544866
Showing the first eight; more decompositions exist.
