Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 177784, here are decompositions:
- 23 + 177761 = 177784
- 41 + 177743 = 177784
- 107 + 177677 = 177784
- 137 + 177647 = 177784
- 251 + 177533 = 177784
- 311 + 177473 = 177784
- 317 + 177467 = 177784
- 353 + 177431 = 177784
Showing the first eight; more decompositions exist.
