Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1021734, here are decompositions:
- 23 + 1021711 = 1021734
- 37 + 1021697 = 1021734
- 61 + 1021673 = 1021734
- 71 + 1021663 = 1021734
- 73 + 1021661 = 1021734
- 83 + 1021651 = 1021734
- 107 + 1021627 = 1021734
- 113 + 1021621 = 1021734
Showing the first eight; more decompositions exist.
