Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8722770, here are decompositions:
- 13 + 8722757 = 8722770
- 31 + 8722739 = 8722770
- 59 + 8722711 = 8722770
- 97 + 8722673 = 8722770
- 109 + 8722661 = 8722770
- 127 + 8722643 = 8722770
- 139 + 8722631 = 8722770
- 149 + 8722621 = 8722770
Showing the first eight; more decompositions exist.
