Also seen as
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 45728, here are decompositions:
- 31 + 45697 = 45728
- 37 + 45691 = 45728
- 61 + 45667 = 45728
- 97 + 45631 = 45728
- 139 + 45589 = 45728
- 367 + 45361 = 45728
- 409 + 45319 = 45728
- 421 + 45307 = 45728
Showing the first eight; more decompositions exist.
