Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 47870, here are decompositions:
- 13 + 47857 = 47870
- 61 + 47809 = 47870
- 73 + 47797 = 47870
- 79 + 47791 = 47870
- 127 + 47743 = 47870
- 157 + 47713 = 47870
- 211 + 47659 = 47870
- 241 + 47629 = 47870
Showing the first eight; more decompositions exist.
