Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 513890, here are decompositions:
- 19 + 513871 = 513890
- 61 + 513829 = 513890
- 109 + 513781 = 513890
- 151 + 513739 = 513890
- 163 + 513727 = 513890
- 193 + 513697 = 513890
- 199 + 513691 = 513890
- 211 + 513679 = 513890
Showing the first eight; more decompositions exist.
