Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 47670, here are decompositions:
- 11 + 47659 = 47670
- 13 + 47657 = 47670
- 17 + 47653 = 47670
- 31 + 47639 = 47670
- 41 + 47629 = 47670
- 47 + 47623 = 47670
- 61 + 47609 = 47670
- 71 + 47599 = 47670
Showing the first eight; more decompositions exist.
