Also seen as
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 40556, here are decompositions:
- 13 + 40543 = 40556
- 37 + 40519 = 40556
- 73 + 40483 = 40556
- 97 + 40459 = 40556
- 127 + 40429 = 40556
- 199 + 40357 = 40556
- 367 + 40189 = 40556
- 379 + 40177 = 40556
Showing the first eight; more decompositions exist.
