Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 77942, here are decompositions:
- 13 + 77929 = 77942
- 43 + 77899 = 77942
- 79 + 77863 = 77942
- 103 + 77839 = 77942
- 181 + 77761 = 77942
- 199 + 77743 = 77942
- 211 + 77731 = 77942
- 223 + 77719 = 77942
Showing the first eight; more decompositions exist.
