Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 6128, here are decompositions:
- 7 + 6121 = 6128
- 37 + 6091 = 6128
- 61 + 6067 = 6128
- 271 + 5857 = 6128
- 277 + 5851 = 6128
- 307 + 5821 = 6128
- 337 + 5791 = 6128
- 349 + 5779 = 6128
Showing the first eight; more decompositions exist.
