Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 177742, here are decompositions:
- 3 + 177739 = 177742
- 269 + 177473 = 177742
- 311 + 177431 = 177742
- 359 + 177383 = 177742
- 419 + 177323 = 177742
- 503 + 177239 = 177742
- 569 + 177173 = 177742
- 641 + 177101 = 177742
Showing the first eight; more decompositions exist.
