Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 64988, here are decompositions:
- 19 + 64969 = 64988
- 37 + 64951 = 64988
- 61 + 64927 = 64988
- 67 + 64921 = 64988
- 97 + 64891 = 64988
- 109 + 64879 = 64988
- 139 + 64849 = 64988
- 241 + 64747 = 64988
Showing the first eight; more decompositions exist.
