Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31527726, here are decompositions:
- 17 + 31527709 = 31527726
- 23 + 31527703 = 31527726
- 29 + 31527697 = 31527726
- 37 + 31527689 = 31527726
- 67 + 31527659 = 31527726
- 149 + 31527577 = 31527726
- 157 + 31527569 = 31527726
- 193 + 31527533 = 31527726
Showing the first eight; more decompositions exist.
