Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 513884, here are decompositions:
- 3 + 513881 = 513884
- 13 + 513871 = 513884
- 43 + 513841 = 513884
- 103 + 513781 = 513884
- 157 + 513727 = 513884
- 193 + 513691 = 513884
- 211 + 513673 = 513884
- 373 + 513511 = 513884
Showing the first eight; more decompositions exist.
