Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 47028, here are decompositions:
- 11 + 47017 = 47028
- 31 + 46997 = 47028
- 71 + 46957 = 47028
- 109 + 46919 = 47028
- 127 + 46901 = 47028
- 139 + 46889 = 47028
- 151 + 46877 = 47028
- 167 + 46861 = 47028
Showing the first eight; more decompositions exist.
