Also seen as
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 17784, here are decompositions:
- 23 + 17761 = 17784
- 37 + 17747 = 17784
- 47 + 17737 = 17784
- 71 + 17713 = 17784
- 101 + 17683 = 17784
- 103 + 17681 = 17784
- 127 + 17657 = 17784
- 157 + 17627 = 17784
Showing the first eight; more decompositions exist.
