Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 15884, here are decompositions:
- 3 + 15881 = 15884
- 7 + 15877 = 15884
- 61 + 15823 = 15884
- 67 + 15817 = 15884
- 97 + 15787 = 15884
- 151 + 15733 = 15884
- 157 + 15727 = 15884
- 223 + 15661 = 15884
Showing the first eight; more decompositions exist.
