Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 17478, here are decompositions:
- 7 + 17471 = 17478
- 11 + 17467 = 17478
- 29 + 17449 = 17478
- 47 + 17431 = 17478
- 59 + 17419 = 17478
- 61 + 17417 = 17478
- 89 + 17389 = 17478
- 101 + 17377 = 17478
Showing the first eight; more decompositions exist.
