Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1025500, here are decompositions:
- 17 + 1025483 = 1025500
- 23 + 1025477 = 1025500
- 41 + 1025459 = 1025500
- 83 + 1025417 = 1025500
- 107 + 1025393 = 1025500
- 149 + 1025351 = 1025500
- 167 + 1025333 = 1025500
- 173 + 1025327 = 1025500
Showing the first eight; more decompositions exist.
