Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 77970, here are decompositions:
- 19 + 77951 = 77970
- 37 + 77933 = 77970
- 41 + 77929 = 77970
- 71 + 77899 = 77970
- 103 + 77867 = 77970
- 107 + 77863 = 77970
- 131 + 77839 = 77970
- 157 + 77813 = 77970
Showing the first eight; more decompositions exist.
