Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 18782, here are decompositions:
- 103 + 18679 = 18782
- 199 + 18583 = 18782
- 229 + 18553 = 18782
- 241 + 18541 = 18782
- 331 + 18451 = 18782
- 349 + 18433 = 18782
- 571 + 18211 = 18782
- 601 + 18181 = 18782
Showing the first eight; more decompositions exist.
