Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 188434, here are decompositions:
- 3 + 188431 = 188434
- 17 + 188417 = 188434
- 83 + 188351 = 188434
- 101 + 188333 = 188434
- 131 + 188303 = 188434
- 173 + 188261 = 188434
- 263 + 188171 = 188434
- 461 + 187973 = 188434
Showing the first eight; more decompositions exist.
