Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1005784, here are decompositions:
- 23 + 1005761 = 1005784
- 83 + 1005701 = 1005784
- 107 + 1005677 = 1005784
- 137 + 1005647 = 1005784
- 167 + 1005617 = 1005784
- 191 + 1005593 = 1005784
- 233 + 1005551 = 1005784
- 257 + 1005527 = 1005784
Showing the first eight; more decompositions exist.
