Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31544586, here are decompositions:
- 13 + 31544573 = 31544586
- 43 + 31544543 = 31544586
- 53 + 31544533 = 31544586
- 193 + 31544393 = 31544586
- 223 + 31544363 = 31544586
- 239 + 31544347 = 31544586
- 263 + 31544323 = 31544586
- 373 + 31544213 = 31544586
Showing the first eight; more decompositions exist.
