Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 45128, here are decompositions:
- 7 + 45121 = 45128
- 67 + 45061 = 45128
- 157 + 44971 = 45128
- 211 + 44917 = 45128
- 241 + 44887 = 45128
- 277 + 44851 = 45128
- 331 + 44797 = 45128
- 487 + 44641 = 45128
Showing the first eight; more decompositions exist.
