Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1008542, here are decompositions:
- 43 + 1008499 = 1008542
- 109 + 1008433 = 1008542
- 163 + 1008379 = 1008542
- 211 + 1008331 = 1008542
- 313 + 1008229 = 1008542
- 349 + 1008193 = 1008542
- 499 + 1008043 = 1008542
- 541 + 1008001 = 1008542
Showing the first eight; more decompositions exist.
