Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 125398, here are decompositions:
- 11 + 125387 = 125398
- 59 + 125339 = 125398
- 137 + 125261 = 125398
- 167 + 125231 = 125398
- 179 + 125219 = 125398
- 191 + 125207 = 125398
- 197 + 125201 = 125398
- 257 + 125141 = 125398
Showing the first eight; more decompositions exist.
