Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31541706, here are decompositions:
- 13 + 31541693 = 31541706
- 29 + 31541677 = 31541706
- 47 + 31541659 = 31541706
- 73 + 31541633 = 31541706
- 109 + 31541597 = 31541706
- 137 + 31541569 = 31541706
- 149 + 31541557 = 31541706
- 179 + 31541527 = 31541706
Showing the first eight; more decompositions exist.
