Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 471138, here are decompositions:
- 37 + 471101 = 471138
- 47 + 471091 = 471138
- 97 + 471041 = 471138
- 131 + 471007 = 471138
- 139 + 470999 = 471138
- 179 + 470959 = 471138
- 181 + 470957 = 471138
- 191 + 470947 = 471138
Showing the first eight; more decompositions exist.
