Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 85470, here are decompositions:
- 17 + 85453 = 85470
- 19 + 85451 = 85470
- 23 + 85447 = 85470
- 31 + 85439 = 85470
- 41 + 85429 = 85470
- 43 + 85427 = 85470
- 59 + 85411 = 85470
- 89 + 85381 = 85470
Showing the first eight; more decompositions exist.
