Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 85506, here are decompositions:
- 19 + 85487 = 85506
- 37 + 85469 = 85506
- 53 + 85453 = 85506
- 59 + 85447 = 85506
- 67 + 85439 = 85506
- 79 + 85427 = 85506
- 137 + 85369 = 85506
- 173 + 85333 = 85506
Showing the first eight; more decompositions exist.
