Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 66672, here are decompositions:
- 19 + 66653 = 66672
- 29 + 66643 = 66672
- 43 + 66629 = 66672
- 71 + 66601 = 66672
- 79 + 66593 = 66672
- 101 + 66571 = 66672
- 103 + 66569 = 66672
- 131 + 66541 = 66672
Showing the first eight; more decompositions exist.
