Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 183442, here are decompositions:
- 3 + 183439 = 183442
- 5 + 183437 = 183442
- 53 + 183389 = 183442
- 59 + 183383 = 183442
- 113 + 183329 = 183442
- 179 + 183263 = 183442
- 239 + 183203 = 183442
- 251 + 183191 = 183442
Showing the first eight; more decompositions exist.
