Also seen as
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 9538, here are decompositions:
- 5 + 9533 = 9538
- 17 + 9521 = 9538
- 41 + 9497 = 9538
- 47 + 9491 = 9538
- 59 + 9479 = 9538
- 71 + 9467 = 9538
- 101 + 9437 = 9538
- 107 + 9431 = 9538
Showing the first eight; more decompositions exist.
