Also seen as
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 42258, here are decompositions:
- 19 + 42239 = 42258
- 31 + 42227 = 42258
- 37 + 42221 = 42258
- 61 + 42197 = 42258
- 71 + 42187 = 42258
- 79 + 42179 = 42258
- 89 + 42169 = 42258
- 101 + 42157 = 42258
Showing the first eight; more decompositions exist.
