Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 125328, here are decompositions:
- 17 + 125311 = 125328
- 29 + 125299 = 125328
- 41 + 125287 = 125328
- 59 + 125269 = 125328
- 67 + 125261 = 125328
- 97 + 125231 = 125328
- 107 + 125221 = 125328
- 109 + 125219 = 125328
Showing the first eight; more decompositions exist.
