Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 477128, here are decompositions:
- 37 + 477091 = 477128
- 97 + 477031 = 477128
- 109 + 477019 = 477128
- 139 + 476989 = 477128
- 151 + 476977 = 477128
- 199 + 476929 = 477128
- 241 + 476887 = 477128
- 277 + 476851 = 477128
Showing the first eight; more decompositions exist.
