Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1006590, here are decompositions:
- 7 + 1006583 = 1006590
- 31 + 1006559 = 1006590
- 43 + 1006547 = 1006590
- 47 + 1006543 = 1006590
- 59 + 1006531 = 1006590
- 83 + 1006507 = 1006590
- 97 + 1006493 = 1006590
- 127 + 1006463 = 1006590
Showing the first eight; more decompositions exist.
