Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 42270, here are decompositions:
- 13 + 42257 = 42270
- 31 + 42239 = 42270
- 43 + 42227 = 42270
- 47 + 42223 = 42270
- 61 + 42209 = 42270
- 73 + 42197 = 42270
- 83 + 42187 = 42270
- 89 + 42181 = 42270
Showing the first eight; more decompositions exist.
