Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 71942, here are decompositions:
- 43 + 71899 = 71942
- 61 + 71881 = 71942
- 181 + 71761 = 71942
- 223 + 71719 = 71942
- 229 + 71713 = 71942
- 271 + 71671 = 71942
- 349 + 71593 = 71942
- 373 + 71569 = 71942
Showing the first eight; more decompositions exist.
