Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31541026, here are decompositions:
- 5 + 31541021 = 31541026
- 47 + 31540979 = 31541026
- 239 + 31540787 = 31541026
- 317 + 31540709 = 31541026
- 347 + 31540679 = 31541026
- 383 + 31540643 = 31541026
- 389 + 31540637 = 31541026
- 683 + 31540343 = 31541026
Showing the first eight; more decompositions exist.
