Also seen as
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 77988, here are decompositions:
- 5 + 77983 = 77988
- 11 + 77977 = 77988
- 19 + 77969 = 77988
- 37 + 77951 = 77988
- 59 + 77929 = 77988
- 89 + 77899 = 77988
- 139 + 77849 = 77988
- 149 + 77839 = 77988
Showing the first eight; more decompositions exist.
