Also seen as
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 42064, here are decompositions:
- 3 + 42061 = 42064
- 41 + 42023 = 42064
- 47 + 42017 = 42064
- 83 + 41981 = 42064
- 107 + 41957 = 42064
- 137 + 41927 = 42064
- 167 + 41897 = 42064
- 251 + 41813 = 42064
Showing the first eight; more decompositions exist.
