Also seen as
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 42402, here are decompositions:
- 5 + 42397 = 42402
- 11 + 42391 = 42402
- 23 + 42379 = 42402
- 29 + 42373 = 42402
- 43 + 42359 = 42402
- 53 + 42349 = 42402
- 71 + 42331 = 42402
- 79 + 42323 = 42402
Showing the first eight; more decompositions exist.
