Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 939420, here are decompositions:
- 7 + 939413 = 939420
- 29 + 939391 = 939420
- 43 + 939377 = 939420
- 47 + 939373 = 939420
- 59 + 939361 = 939420
- 61 + 939359 = 939420
- 71 + 939349 = 939420
- 73 + 939347 = 939420
Showing the first eight; more decompositions exist.
