Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1023490, here are decompositions:
- 3 + 1023487 = 1023490
- 23 + 1023467 = 1023490
- 29 + 1023461 = 1023490
- 71 + 1023419 = 1023490
- 101 + 1023389 = 1023490
- 137 + 1023353 = 1023490
- 173 + 1023317 = 1023490
- 179 + 1023311 = 1023490
Showing the first eight; more decompositions exist.
