Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 10638, here are decompositions:
- 7 + 10631 = 10638
- 11 + 10627 = 10638
- 31 + 10607 = 10638
- 37 + 10601 = 10638
- 41 + 10597 = 10638
- 71 + 10567 = 10638
- 79 + 10559 = 10638
- 107 + 10531 = 10638
Showing the first eight; more decompositions exist.
