Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 42070, here are decompositions:
- 47 + 42023 = 42070
- 53 + 42017 = 42070
- 71 + 41999 = 42070
- 89 + 41981 = 42070
- 101 + 41969 = 42070
- 113 + 41957 = 42070
- 167 + 41903 = 42070
- 173 + 41897 = 42070
Showing the first eight; more decompositions exist.
