Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 63842, here are decompositions:
- 3 + 63839 = 63842
- 19 + 63823 = 63842
- 43 + 63799 = 63842
- 61 + 63781 = 63842
- 139 + 63703 = 63842
- 151 + 63691 = 63842
- 193 + 63649 = 63842
- 241 + 63601 = 63842
Showing the first eight; more decompositions exist.
