Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 66394, here are decompositions:
- 11 + 66383 = 66394
- 17 + 66377 = 66394
- 47 + 66347 = 66394
- 101 + 66293 = 66394
- 173 + 66221 = 66394
- 233 + 66161 = 66394
- 257 + 66137 = 66394
- 311 + 66083 = 66394
Showing the first eight; more decompositions exist.
