Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 125370, here are decompositions:
- 17 + 125353 = 125370
- 31 + 125339 = 125370
- 41 + 125329 = 125370
- 59 + 125311 = 125370
- 67 + 125303 = 125370
- 71 + 125299 = 125370
- 83 + 125287 = 125370
- 101 + 125269 = 125370
Showing the first eight; more decompositions exist.
