Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 89040, here are decompositions:
- 19 + 89021 = 89040
- 23 + 89017 = 89040
- 31 + 89009 = 89040
- 37 + 89003 = 89040
- 43 + 88997 = 89040
- 47 + 88993 = 89040
- 71 + 88969 = 89040
- 89 + 88951 = 89040
Showing the first eight; more decompositions exist.
