Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 42844, here are decompositions:
- 3 + 42841 = 42844
- 5 + 42839 = 42844
- 23 + 42821 = 42844
- 47 + 42797 = 42844
- 71 + 42773 = 42844
- 101 + 42743 = 42844
- 107 + 42737 = 42844
- 167 + 42677 = 42844
Showing the first eight; more decompositions exist.
