Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1008540, here are decompositions:
- 23 + 1008517 = 1008540
- 37 + 1008503 = 1008540
- 41 + 1008499 = 1008540
- 47 + 1008493 = 1008540
- 73 + 1008467 = 1008540
- 89 + 1008451 = 1008540
- 103 + 1008437 = 1008540
- 107 + 1008433 = 1008540
Showing the first eight; more decompositions exist.
