Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 189126, here are decompositions:
- 59 + 189067 = 189126
- 83 + 189043 = 189126
- 107 + 189019 = 189126
- 109 + 189017 = 189126
- 127 + 188999 = 189126
- 173 + 188953 = 189126
- 193 + 188933 = 189126
- 199 + 188927 = 189126
Showing the first eight; more decompositions exist.
