Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 47864, here are decompositions:
- 7 + 47857 = 47864
- 67 + 47797 = 47864
- 73 + 47791 = 47864
- 127 + 47737 = 47864
- 151 + 47713 = 47864
- 163 + 47701 = 47864
- 211 + 47653 = 47864
- 241 + 47623 = 47864
Showing the first eight; more decompositions exist.
