Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 42404, here are decompositions:
- 7 + 42397 = 42404
- 13 + 42391 = 42404
- 31 + 42373 = 42404
- 67 + 42337 = 42404
- 73 + 42331 = 42404
- 97 + 42307 = 42404
- 181 + 42223 = 42404
- 211 + 42193 = 42404
Showing the first eight; more decompositions exist.
