Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 42250, here are decompositions:
- 11 + 42239 = 42250
- 23 + 42227 = 42250
- 29 + 42221 = 42250
- 41 + 42209 = 42250
- 53 + 42197 = 42250
- 71 + 42179 = 42250
- 149 + 42101 = 42250
- 167 + 42083 = 42250
Showing the first eight; more decompositions exist.
