Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 513722, here are decompositions:
- 3 + 513719 = 513722
- 31 + 513691 = 513722
- 43 + 513679 = 513722
- 73 + 513649 = 513722
- 193 + 513529 = 513722
- 211 + 513511 = 513722
- 241 + 513481 = 513722
- 283 + 513439 = 513722
Showing the first eight; more decompositions exist.
