Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 90558, here are decompositions:
- 11 + 90547 = 90558
- 29 + 90529 = 90558
- 31 + 90527 = 90558
- 47 + 90511 = 90558
- 59 + 90499 = 90558
- 89 + 90469 = 90558
- 151 + 90407 = 90558
- 157 + 90401 = 90558
Showing the first eight; more decompositions exist.
