Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 76128, here are decompositions:
- 5 + 76123 = 76128
- 29 + 76099 = 76128
- 37 + 76091 = 76128
- 47 + 76081 = 76128
- 89 + 76039 = 76128
- 97 + 76031 = 76128
- 127 + 76001 = 76128
- 131 + 75997 = 76128
Showing the first eight; more decompositions exist.
