Also seen as
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 49666, here are decompositions:
- 3 + 49663 = 49666
- 53 + 49613 = 49666
- 107 + 49559 = 49666
- 137 + 49529 = 49666
- 167 + 49499 = 49666
- 233 + 49433 = 49666
- 257 + 49409 = 49666
- 359 + 49307 = 49666
Showing the first eight; more decompositions exist.
