Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 66150, here are decompositions:
- 13 + 66137 = 66150
- 41 + 66109 = 66150
- 43 + 66107 = 66150
- 47 + 66103 = 66150
- 61 + 66089 = 66150
- 67 + 66083 = 66150
- 79 + 66071 = 66150
- 83 + 66067 = 66150
Showing the first eight; more decompositions exist.
