Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 175138, here are decompositions:
- 59 + 175079 = 175138
- 71 + 175067 = 175138
- 149 + 174989 = 175138
- 179 + 174959 = 175138
- 317 + 174821 = 175138
- 389 + 174749 = 175138
- 401 + 174737 = 175138
- 479 + 174659 = 175138
Showing the first eight; more decompositions exist.
