Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 19482, here are decompositions:
- 5 + 19477 = 19482
- 11 + 19471 = 19482
- 13 + 19469 = 19482
- 19 + 19463 = 19482
- 41 + 19441 = 19482
- 53 + 19429 = 19482
- 59 + 19423 = 19482
- 61 + 19421 = 19482
Showing the first eight; more decompositions exist.
