Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 509784, here are decompositions:
- 17 + 509767 = 509784
- 43 + 509741 = 509784
- 47 + 509737 = 509784
- 53 + 509731 = 509784
- 61 + 509723 = 509784
- 97 + 509687 = 509784
- 103 + 509681 = 509784
- 131 + 509653 = 509784
Showing the first eight; more decompositions exist.
