Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 68020, here are decompositions:
- 41 + 67979 = 68020
- 53 + 67967 = 68020
- 59 + 67961 = 68020
- 89 + 67931 = 68020
- 137 + 67883 = 68020
- 167 + 67853 = 68020
- 191 + 67829 = 68020
- 257 + 67763 = 68020
Showing the first eight; more decompositions exist.
