Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 189148, here are decompositions:
- 107 + 189041 = 189148
- 131 + 189017 = 189148
- 137 + 189011 = 189148
- 149 + 188999 = 189148
- 191 + 188957 = 189148
- 257 + 188891 = 189148
- 317 + 188831 = 189148
- 347 + 188801 = 189148
Showing the first eight; more decompositions exist.
