Also seen as
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 47778, here are decompositions:
- 37 + 47741 = 47778
- 41 + 47737 = 47778
- 61 + 47717 = 47778
- 67 + 47711 = 47778
- 79 + 47699 = 47778
- 97 + 47681 = 47778
- 139 + 47639 = 47778
- 149 + 47629 = 47778
Showing the first eight; more decompositions exist.
