Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 64042, here are decompositions:
- 5 + 64037 = 64042
- 23 + 64019 = 64042
- 29 + 64013 = 64042
- 113 + 63929 = 64042
- 179 + 63863 = 64042
- 233 + 63809 = 64042
- 239 + 63803 = 64042
- 269 + 63773 = 64042
Showing the first eight; more decompositions exist.
