Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 15854, here are decompositions:
- 31 + 15823 = 15854
- 37 + 15817 = 15854
- 67 + 15787 = 15854
- 127 + 15727 = 15854
- 193 + 15661 = 15854
- 211 + 15643 = 15854
- 271 + 15583 = 15854
- 313 + 15541 = 15854
Showing the first eight; more decompositions exist.
