Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 68042, here are decompositions:
- 19 + 68023 = 68042
- 103 + 67939 = 68042
- 109 + 67933 = 68042
- 151 + 67891 = 68042
- 199 + 67843 = 68042
- 223 + 67819 = 68042
- 241 + 67801 = 68042
- 283 + 67759 = 68042
Showing the first eight; more decompositions exist.
