Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 175742, here are decompositions:
- 19 + 175723 = 175742
- 43 + 175699 = 175742
- 79 + 175663 = 175742
- 109 + 175633 = 175742
- 199 + 175543 = 175742
- 223 + 175519 = 175742
- 331 + 175411 = 175742
- 349 + 175393 = 175742
Showing the first eight; more decompositions exist.
