Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 66146, here are decompositions:
- 37 + 66109 = 66146
- 43 + 66103 = 66146
- 79 + 66067 = 66146
- 109 + 66037 = 66146
- 163 + 65983 = 66146
- 307 + 65839 = 66146
- 337 + 65809 = 66146
- 433 + 65713 = 66146
Showing the first eight; more decompositions exist.
