Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 15844, here are decompositions:
- 41 + 15803 = 15844
- 47 + 15797 = 15844
- 53 + 15791 = 15844
- 71 + 15773 = 15844
- 83 + 15761 = 15844
- 107 + 15737 = 15844
- 113 + 15731 = 15844
- 173 + 15671 = 15844
Showing the first eight; more decompositions exist.
