Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1047540, here are decompositions:
- 7 + 1047533 = 1047540
- 29 + 1047511 = 1047540
- 41 + 1047499 = 1047540
- 61 + 1047479 = 1047540
- 71 + 1047469 = 1047540
- 73 + 1047467 = 1047540
- 149 + 1047391 = 1047540
- 167 + 1047373 = 1047540
Showing the first eight; more decompositions exist.
