Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 177552, here are decompositions:
- 13 + 177539 = 177552
- 19 + 177533 = 177552
- 41 + 177511 = 177552
- 59 + 177493 = 177552
- 71 + 177481 = 177552
- 79 + 177473 = 177552
- 131 + 177421 = 177552
- 173 + 177379 = 177552
Showing the first eight; more decompositions exist.
