Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 19782, here are decompositions:
- 5 + 19777 = 19782
- 19 + 19763 = 19782
- 23 + 19759 = 19782
- 29 + 19753 = 19782
- 31 + 19751 = 19782
- 43 + 19739 = 19782
- 73 + 19709 = 19782
- 83 + 19699 = 19782
Showing the first eight; more decompositions exist.
