Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 188856, here are decompositions:
- 13 + 188843 = 188856
- 23 + 188833 = 188856
- 29 + 188827 = 188856
- 89 + 188767 = 188856
- 103 + 188753 = 188856
- 127 + 188729 = 188856
- 137 + 188719 = 188856
- 149 + 188707 = 188856
Showing the first eight; more decompositions exist.
