Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 47930, here are decompositions:
- 13 + 47917 = 47930
- 19 + 47911 = 47930
- 61 + 47869 = 47930
- 73 + 47857 = 47930
- 139 + 47791 = 47930
- 151 + 47779 = 47930
- 193 + 47737 = 47930
- 229 + 47701 = 47930
Showing the first eight; more decompositions exist.
