Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 89280, here are decompositions:
- 7 + 89273 = 89280
- 11 + 89269 = 89280
- 19 + 89261 = 89280
- 43 + 89237 = 89280
- 53 + 89227 = 89280
- 67 + 89213 = 89280
- 71 + 89209 = 89280
- 127 + 89153 = 89280
Showing the first eight; more decompositions exist.
