Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 42378, here are decompositions:
- 5 + 42373 = 42378
- 19 + 42359 = 42378
- 29 + 42349 = 42378
- 41 + 42337 = 42378
- 47 + 42331 = 42378
- 71 + 42307 = 42378
- 79 + 42299 = 42378
- 97 + 42281 = 42378
Showing the first eight; more decompositions exist.
