Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 3472, here are decompositions:
- 3 + 3469 = 3472
- 5 + 3467 = 3472
- 11 + 3461 = 3472
- 23 + 3449 = 3472
- 59 + 3413 = 3472
- 83 + 3389 = 3472
- 101 + 3371 = 3472
- 113 + 3359 = 3472
Showing the first eight; more decompositions exist.
