Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 189108, here are decompositions:
- 41 + 189067 = 189108
- 47 + 189061 = 189108
- 67 + 189041 = 189108
- 89 + 189019 = 189108
- 97 + 189011 = 189108
- 109 + 188999 = 189108
- 151 + 188957 = 189108
- 167 + 188941 = 189108
Showing the first eight; more decompositions exist.
