Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 64040, here are decompositions:
- 3 + 64037 = 64040
- 7 + 64033 = 64040
- 43 + 63997 = 64040
- 127 + 63913 = 64040
- 139 + 63901 = 64040
- 199 + 63841 = 64040
- 241 + 63799 = 64040
- 313 + 63727 = 64040
Showing the first eight; more decompositions exist.
