Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 125284, here are decompositions:
- 23 + 125261 = 125284
- 41 + 125243 = 125284
- 53 + 125231 = 125284
- 83 + 125201 = 125284
- 101 + 125183 = 125284
- 167 + 125117 = 125284
- 191 + 125093 = 125284
- 281 + 125003 = 125284
Showing the first eight; more decompositions exist.
