Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 77946, here are decompositions:
- 13 + 77933 = 77946
- 17 + 77929 = 77946
- 47 + 77899 = 77946
- 53 + 77893 = 77946
- 79 + 77867 = 77946
- 83 + 77863 = 77946
- 97 + 77849 = 77946
- 107 + 77839 = 77946
Showing the first eight; more decompositions exist.
