Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1025492, here are decompositions:
- 73 + 1025419 = 1025492
- 79 + 1025413 = 1025492
- 109 + 1025383 = 1025492
- 211 + 1025281 = 1025492
- 283 + 1025209 = 1025492
- 331 + 1025161 = 1025492
- 373 + 1025119 = 1025492
- 379 + 1025113 = 1025492
Showing the first eight; more decompositions exist.
