Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 39784, here are decompositions:
- 5 + 39779 = 39784
- 23 + 39761 = 39784
- 113 + 39671 = 39784
- 233 + 39551 = 39784
- 263 + 39521 = 39784
- 281 + 39503 = 39784
- 401 + 39383 = 39784
- 443 + 39341 = 39784
Showing the first eight; more decompositions exist.
