Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 42452, here are decompositions:
- 19 + 42433 = 42452
- 43 + 42409 = 42452
- 61 + 42391 = 42452
- 73 + 42379 = 42452
- 79 + 42373 = 42452
- 103 + 42349 = 42452
- 229 + 42223 = 42452
- 271 + 42181 = 42452
Showing the first eight; more decompositions exist.
