Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 45028, here are decompositions:
- 41 + 44987 = 45028
- 89 + 44939 = 45028
- 101 + 44927 = 45028
- 149 + 44879 = 45028
- 239 + 44789 = 45028
- 251 + 44777 = 45028
- 257 + 44771 = 45028
- 317 + 44711 = 45028
Showing the first eight; more decompositions exist.
