Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31544842, here are decompositions:
- 23 + 31544819 = 31544842
- 59 + 31544783 = 31544842
- 71 + 31544771 = 31544842
- 83 + 31544759 = 31544842
- 269 + 31544573 = 31544842
- 281 + 31544561 = 31544842
- 311 + 31544531 = 31544842
- 449 + 31544393 = 31544842
Showing the first eight; more decompositions exist.
