Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31466942, here are decompositions:
- 43 + 31466899 = 31466942
- 151 + 31466791 = 31466942
- 193 + 31466749 = 31466942
- 211 + 31466731 = 31466942
- 223 + 31466719 = 31466942
- 229 + 31466713 = 31466942
- 271 + 31466671 = 31466942
- 313 + 31466629 = 31466942
Showing the first eight; more decompositions exist.
