Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 18844, here are decompositions:
- 5 + 18839 = 18844
- 41 + 18803 = 18844
- 47 + 18797 = 18844
- 71 + 18773 = 18844
- 101 + 18743 = 18844
- 113 + 18731 = 18844
- 131 + 18713 = 18844
- 173 + 18671 = 18844
Showing the first eight; more decompositions exist.
