Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 77966, here are decompositions:
- 37 + 77929 = 77966
- 67 + 77899 = 77966
- 73 + 77893 = 77966
- 103 + 77863 = 77966
- 127 + 77839 = 77966
- 193 + 77773 = 77966
- 223 + 77743 = 77966
- 277 + 77689 = 77966
Showing the first eight; more decompositions exist.
