Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 91644, here are decompositions:
- 5 + 91639 = 91644
- 13 + 91631 = 91644
- 23 + 91621 = 91644
- 53 + 91591 = 91644
- 61 + 91583 = 91644
- 67 + 91577 = 91644
- 71 + 91573 = 91644
- 73 + 91571 = 91644
Showing the first eight; more decompositions exist.
