Also seen as
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2784, here are decompositions:
- 7 + 2777 = 2784
- 17 + 2767 = 2784
- 31 + 2753 = 2784
- 43 + 2741 = 2784
- 53 + 2731 = 2784
- 71 + 2713 = 2784
- 73 + 2711 = 2784
- 97 + 2687 = 2784
Showing the first eight; more decompositions exist.
