Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 85988, here are decompositions:
- 79 + 85909 = 85988
- 151 + 85837 = 85988
- 157 + 85831 = 85988
- 271 + 85717 = 85988
- 277 + 85711 = 85988
- 349 + 85639 = 85988
- 367 + 85621 = 85988
- 439 + 85549 = 85988
Showing the first eight; more decompositions exist.
