Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 67188, here are decompositions:
- 7 + 67181 = 67188
- 19 + 67169 = 67188
- 31 + 67157 = 67188
- 47 + 67141 = 67188
- 59 + 67129 = 67188
- 67 + 67121 = 67188
- 109 + 67079 = 67188
- 127 + 67061 = 67188
Showing the first eight; more decompositions exist.
