Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 17442, here are decompositions:
- 11 + 17431 = 17442
- 23 + 17419 = 17442
- 41 + 17401 = 17442
- 53 + 17389 = 17442
- 59 + 17383 = 17442
- 83 + 17359 = 17442
- 101 + 17341 = 17442
- 109 + 17333 = 17442
Showing the first eight; more decompositions exist.
