Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 64138, here are decompositions:
- 29 + 64109 = 64138
- 47 + 64091 = 64138
- 71 + 64067 = 64138
- 101 + 64037 = 64138
- 131 + 64007 = 64138
- 281 + 63857 = 64138
- 401 + 63737 = 64138
- 419 + 63719 = 64138
Showing the first eight; more decompositions exist.
