Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 494424, here are decompositions:
- 11 + 494413 = 494424
- 17 + 494407 = 494424
- 37 + 494387 = 494424
- 41 + 494383 = 494424
- 43 + 494381 = 494424
- 71 + 494353 = 494424
- 83 + 494341 = 494424
- 97 + 494327 = 494424
Showing the first eight; more decompositions exist.
