Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 3228, here are decompositions:
- 7 + 3221 = 3228
- 11 + 3217 = 3228
- 19 + 3209 = 3228
- 37 + 3191 = 3228
- 41 + 3187 = 3228
- 47 + 3181 = 3228
- 59 + 3169 = 3228
- 61 + 3167 = 3228
Showing the first eight; more decompositions exist.
