Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 125392, here are decompositions:
- 5 + 125387 = 125392
- 53 + 125339 = 125392
- 89 + 125303 = 125392
- 131 + 125261 = 125392
- 149 + 125243 = 125392
- 173 + 125219 = 125392
- 191 + 125201 = 125392
- 251 + 125141 = 125392
Showing the first eight; more decompositions exist.
