Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 42506, here are decompositions:
- 7 + 42499 = 42506
- 19 + 42487 = 42506
- 43 + 42463 = 42506
- 73 + 42433 = 42506
- 97 + 42409 = 42506
- 103 + 42403 = 42506
- 109 + 42397 = 42506
- 127 + 42379 = 42506
Showing the first eight; more decompositions exist.
