Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 125488, here are decompositions:
- 17 + 125471 = 125488
- 47 + 125441 = 125488
- 59 + 125429 = 125488
- 89 + 125399 = 125488
- 101 + 125387 = 125488
- 149 + 125339 = 125488
- 227 + 125261 = 125488
- 257 + 125231 = 125488
Showing the first eight; more decompositions exist.
