Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 85500, here are decompositions:
- 13 + 85487 = 85500
- 31 + 85469 = 85500
- 47 + 85453 = 85500
- 53 + 85447 = 85500
- 61 + 85439 = 85500
- 71 + 85429 = 85500
- 73 + 85427 = 85500
- 89 + 85411 = 85500
Showing the first eight; more decompositions exist.
