Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 66012, here are decompositions:
- 19 + 65993 = 66012
- 29 + 65983 = 66012
- 31 + 65981 = 66012
- 61 + 65951 = 66012
- 83 + 65929 = 66012
- 113 + 65899 = 66012
- 131 + 65881 = 66012
- 173 + 65839 = 66012
Showing the first eight; more decompositions exist.
