Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 128104, here are decompositions:
- 5 + 128099 = 128104
- 71 + 128033 = 128104
- 83 + 128021 = 128104
- 107 + 127997 = 128104
- 131 + 127973 = 128104
- 173 + 127931 = 128104
- 191 + 127913 = 128104
- 227 + 127877 = 128104
Showing the first eight; more decompositions exist.
