Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 64166, here are decompositions:
- 13 + 64153 = 64166
- 43 + 64123 = 64166
- 103 + 64063 = 64166
- 313 + 63853 = 64166
- 367 + 63799 = 64166
- 373 + 63793 = 64166
- 439 + 63727 = 64166
- 457 + 63709 = 64166
Showing the first eight; more decompositions exist.
