Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 68004, here are decompositions:
- 11 + 67993 = 68004
- 17 + 67987 = 68004
- 37 + 67967 = 68004
- 43 + 67961 = 68004
- 47 + 67957 = 68004
- 61 + 67943 = 68004
- 71 + 67933 = 68004
- 73 + 67931 = 68004
Showing the first eight; more decompositions exist.
