Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 67220, here are decompositions:
- 3 + 67217 = 67220
- 7 + 67213 = 67220
- 31 + 67189 = 67220
- 67 + 67153 = 67220
- 79 + 67141 = 67220
- 163 + 67057 = 67220
- 199 + 67021 = 67220
- 271 + 66949 = 67220
Showing the first eight; more decompositions exist.
