Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1025490, here are decompositions:
- 7 + 1025483 = 1025490
- 13 + 1025477 = 1025490
- 31 + 1025459 = 1025490
- 47 + 1025443 = 1025490
- 71 + 1025419 = 1025490
- 73 + 1025417 = 1025490
- 83 + 1025407 = 1025490
- 97 + 1025393 = 1025490
Showing the first eight; more decompositions exist.
