Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 42228, here are decompositions:
- 5 + 42223 = 42228
- 7 + 42221 = 42228
- 19 + 42209 = 42228
- 31 + 42197 = 42228
- 41 + 42187 = 42228
- 47 + 42181 = 42228
- 59 + 42169 = 42228
- 71 + 42157 = 42228
Showing the first eight; more decompositions exist.
