Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 45556, here are decompositions:
- 3 + 45553 = 45556
- 23 + 45533 = 45556
- 53 + 45503 = 45556
- 59 + 45497 = 45556
- 167 + 45389 = 45556
- 179 + 45377 = 45556
- 227 + 45329 = 45556
- 239 + 45317 = 45556
Showing the first eight; more decompositions exist.
