Also seen as
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 67428, here are decompositions:
- 7 + 67421 = 67428
- 17 + 67411 = 67428
- 19 + 67409 = 67428
- 29 + 67399 = 67428
- 37 + 67391 = 67428
- 59 + 67369 = 67428
- 79 + 67349 = 67428
- 89 + 67339 = 67428
Showing the first eight; more decompositions exist.
