Also seen as
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 40030, here are decompositions:
- 17 + 40013 = 40030
- 41 + 39989 = 40030
- 47 + 39983 = 40030
- 59 + 39971 = 40030
- 101 + 39929 = 40030
- 167 + 39863 = 40030
- 173 + 39857 = 40030
- 191 + 39839 = 40030
Showing the first eight; more decompositions exist.
