Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 163844, here are decompositions:
- 3 + 163841 = 163844
- 73 + 163771 = 163844
- 103 + 163741 = 163844
- 211 + 163633 = 163844
- 223 + 163621 = 163844
- 271 + 163573 = 163844
- 277 + 163567 = 163844
- 283 + 163561 = 163844
Showing the first eight; more decompositions exist.
