Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 85566, here are decompositions:
- 17 + 85549 = 85566
- 43 + 85523 = 85566
- 53 + 85513 = 85566
- 79 + 85487 = 85566
- 97 + 85469 = 85566
- 113 + 85453 = 85566
- 127 + 85439 = 85566
- 137 + 85429 = 85566
Showing the first eight; more decompositions exist.
