Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 177778, here are decompositions:
- 17 + 177761 = 177778
- 101 + 177677 = 177778
- 131 + 177647 = 177778
- 239 + 177539 = 177778
- 311 + 177467 = 177778
- 347 + 177431 = 177778
- 431 + 177347 = 177778
- 509 + 177269 = 177778
Showing the first eight; more decompositions exist.
