Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 105088, here are decompositions:
- 17 + 105071 = 105088
- 89 + 104999 = 105088
- 101 + 104987 = 105088
- 197 + 104891 = 105088
- 239 + 104849 = 105088
- 257 + 104831 = 105088
- 359 + 104729 = 105088
- 449 + 104639 = 105088
Showing the first eight; more decompositions exist.
