Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 91638, here are decompositions:
- 7 + 91631 = 91638
- 17 + 91621 = 91638
- 47 + 91591 = 91638
- 61 + 91577 = 91638
- 67 + 91571 = 91638
- 97 + 91541 = 91638
- 109 + 91529 = 91638
- 139 + 91499 = 91638
Showing the first eight; more decompositions exist.
