Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31536568, here are decompositions:
- 17 + 31536551 = 31536568
- 29 + 31536539 = 31536568
- 47 + 31536521 = 31536568
- 281 + 31536287 = 31536568
- 467 + 31536101 = 31536568
- 587 + 31535981 = 31536568
- 659 + 31535909 = 31536568
- 821 + 31535747 = 31536568
Showing the first eight; more decompositions exist.
