Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 518364, here are decompositions:
- 23 + 518341 = 518364
- 37 + 518327 = 518364
- 53 + 518311 = 518364
- 73 + 518291 = 518364
- 103 + 518261 = 518364
- 127 + 518237 = 518364
- 131 + 518233 = 518364
- 157 + 518207 = 518364
Showing the first eight; more decompositions exist.
