Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 78382, here are decompositions:
- 41 + 78341 = 78382
- 71 + 78311 = 78382
- 149 + 78233 = 78382
- 179 + 78203 = 78382
- 191 + 78191 = 78382
- 281 + 78101 = 78382
- 383 + 77999 = 78382
- 431 + 77951 = 78382
Showing the first eight; more decompositions exist.
