Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1003806, here are decompositions:
- 19 + 1003787 = 1003806
- 43 + 1003763 = 1003806
- 53 + 1003753 = 1003806
- 59 + 1003747 = 1003806
- 73 + 1003733 = 1003806
- 113 + 1003693 = 1003806
- 127 + 1003679 = 1003806
- 179 + 1003627 = 1003806
Showing the first eight; more decompositions exist.
