Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 66090, here are decompositions:
- 7 + 66083 = 66090
- 19 + 66071 = 66090
- 23 + 66067 = 66090
- 43 + 66047 = 66090
- 53 + 66037 = 66090
- 61 + 66029 = 66090
- 97 + 65993 = 66090
- 107 + 65983 = 66090
Showing the first eight; more decompositions exist.
