Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 125508, here are decompositions:
- 11 + 125497 = 125508
- 37 + 125471 = 125508
- 67 + 125441 = 125508
- 79 + 125429 = 125508
- 101 + 125407 = 125508
- 109 + 125399 = 125508
- 137 + 125371 = 125508
- 179 + 125329 = 125508
Showing the first eight; more decompositions exist.
