Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 85518, here are decompositions:
- 5 + 85513 = 85518
- 31 + 85487 = 85518
- 67 + 85451 = 85518
- 71 + 85447 = 85518
- 79 + 85439 = 85518
- 89 + 85429 = 85518
- 107 + 85411 = 85518
- 137 + 85381 = 85518
Showing the first eight; more decompositions exist.
