Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 9500, here are decompositions:
- 3 + 9497 = 9500
- 37 + 9463 = 9500
- 61 + 9439 = 9500
- 67 + 9433 = 9500
- 79 + 9421 = 9500
- 97 + 9403 = 9500
- 103 + 9397 = 9500
- 109 + 9391 = 9500
Showing the first eight; more decompositions exist.
