Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 128034, here are decompositions:
- 13 + 128021 = 128034
- 37 + 127997 = 128034
- 61 + 127973 = 128034
- 83 + 127951 = 128034
- 103 + 127931 = 128034
- 113 + 127921 = 128034
- 157 + 127877 = 128034
- 167 + 127867 = 128034
Showing the first eight; more decompositions exist.
