Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 178524, here are decompositions:
- 11 + 178513 = 178524
- 23 + 178501 = 178524
- 37 + 178487 = 178524
- 43 + 178481 = 178524
- 83 + 178441 = 178524
- 107 + 178417 = 178524
- 127 + 178397 = 178524
- 131 + 178393 = 178524
Showing the first eight; more decompositions exist.
