Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 47718, here are decompositions:
- 5 + 47713 = 47718
- 7 + 47711 = 47718
- 17 + 47701 = 47718
- 19 + 47699 = 47718
- 37 + 47681 = 47718
- 59 + 47659 = 47718
- 61 + 47657 = 47718
- 79 + 47639 = 47718
Showing the first eight; more decompositions exist.
