Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 15874, here are decompositions:
- 71 + 15803 = 15874
- 83 + 15791 = 15874
- 101 + 15773 = 15874
- 107 + 15767 = 15874
- 113 + 15761 = 15874
- 137 + 15737 = 15874
- 191 + 15683 = 15874
- 227 + 15647 = 15874
Showing the first eight; more decompositions exist.
