Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 85560, here are decompositions:
- 11 + 85549 = 85560
- 29 + 85531 = 85560
- 37 + 85523 = 85560
- 43 + 85517 = 85560
- 47 + 85513 = 85560
- 73 + 85487 = 85560
- 107 + 85453 = 85560
- 109 + 85451 = 85560
Showing the first eight; more decompositions exist.
