Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 66288, here are decompositions:
- 17 + 66271 = 66288
- 67 + 66221 = 66288
- 97 + 66191 = 66288
- 109 + 66179 = 66288
- 127 + 66161 = 66288
- 151 + 66137 = 66288
- 179 + 66109 = 66288
- 181 + 66107 = 66288
Showing the first eight; more decompositions exist.
