Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 15790, here are decompositions:
- 3 + 15787 = 15790
- 17 + 15773 = 15790
- 23 + 15767 = 15790
- 29 + 15761 = 15790
- 41 + 15749 = 15790
- 53 + 15737 = 15790
- 59 + 15731 = 15790
- 107 + 15683 = 15790
Showing the first eight; more decompositions exist.
