Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 177538, here are decompositions:
- 5 + 177533 = 177538
- 71 + 177467 = 177538
- 107 + 177431 = 177538
- 191 + 177347 = 177538
- 269 + 177269 = 177538
- 281 + 177257 = 177538
- 587 + 176951 = 177538
- 617 + 176921 = 177538
Showing the first eight; more decompositions exist.
