Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 87844, here are decompositions:
- 11 + 87833 = 87844
- 41 + 87803 = 87844
- 47 + 87797 = 87844
- 101 + 87743 = 87844
- 173 + 87671 = 87844
- 257 + 87587 = 87844
- 353 + 87491 = 87844
- 401 + 87443 = 87844
Showing the first eight; more decompositions exist.
