Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 939474, here are decompositions:
- 5 + 939469 = 939474
- 23 + 939451 = 939474
- 31 + 939443 = 939474
- 43 + 939431 = 939474
- 61 + 939413 = 939474
- 83 + 939391 = 939474
- 97 + 939377 = 939474
- 101 + 939373 = 939474
Showing the first eight; more decompositions exist.
