Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 7784, here are decompositions:
- 31 + 7753 = 7784
- 43 + 7741 = 7784
- 61 + 7723 = 7784
- 67 + 7717 = 7784
- 97 + 7687 = 7784
- 103 + 7681 = 7784
- 163 + 7621 = 7784
- 181 + 7603 = 7784
Showing the first eight; more decompositions exist.
