Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 66126, here are decompositions:
- 17 + 66109 = 66126
- 19 + 66107 = 66126
- 23 + 66103 = 66126
- 37 + 66089 = 66126
- 43 + 66083 = 66126
- 59 + 66067 = 66126
- 79 + 66047 = 66126
- 89 + 66037 = 66126
Showing the first eight; more decompositions exist.
