Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 125188, here are decompositions:
- 5 + 125183 = 125188
- 47 + 125141 = 125188
- 71 + 125117 = 125188
- 197 + 124991 = 125188
- 269 + 124919 = 125188
- 281 + 124907 = 125188
- 389 + 124799 = 125188
- 419 + 124769 = 125188
Showing the first eight; more decompositions exist.
