Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 13784, here are decompositions:
- 3 + 13781 = 13784
- 61 + 13723 = 13784
- 73 + 13711 = 13784
- 97 + 13687 = 13784
- 103 + 13681 = 13784
- 151 + 13633 = 13784
- 157 + 13627 = 13784
- 193 + 13591 = 13784
Showing the first eight; more decompositions exist.
