Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 177472, here are decompositions:
- 5 + 177467 = 177472
- 41 + 177431 = 177472
- 89 + 177383 = 177472
- 149 + 177323 = 177472
- 233 + 177239 = 177472
- 263 + 177209 = 177472
- 359 + 177113 = 177472
- 461 + 177011 = 177472
Showing the first eight; more decompositions exist.
