Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 125272, here are decompositions:
- 3 + 125269 = 125272
- 11 + 125261 = 125272
- 29 + 125243 = 125272
- 41 + 125231 = 125272
- 53 + 125219 = 125272
- 71 + 125201 = 125272
- 89 + 125183 = 125272
- 131 + 125141 = 125272
Showing the first eight; more decompositions exist.
