Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 39142, here are decompositions:
- 3 + 39139 = 39142
- 23 + 39119 = 39142
- 29 + 39113 = 39142
- 53 + 39089 = 39142
- 101 + 39041 = 39142
- 149 + 38993 = 39142
- 239 + 38903 = 39142
- 251 + 38891 = 39142
Showing the first eight; more decompositions exist.
