Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 42446, here are decompositions:
- 3 + 42443 = 42446
- 13 + 42433 = 42446
- 37 + 42409 = 42446
- 43 + 42403 = 42446
- 67 + 42379 = 42446
- 73 + 42373 = 42446
- 97 + 42349 = 42446
- 109 + 42337 = 42446
Showing the first eight; more decompositions exist.
