Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1011780, here are decompositions:
- 17 + 1011763 = 1011780
- 31 + 1011749 = 1011780
- 43 + 1011737 = 1011780
- 47 + 1011733 = 1011780
- 61 + 1011719 = 1011780
- 83 + 1011697 = 1011780
- 103 + 1011677 = 1011780
- 109 + 1011671 = 1011780
Showing the first eight; more decompositions exist.
