Also seen as
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 10138, here are decompositions:
- 5 + 10133 = 10138
- 47 + 10091 = 10138
- 59 + 10079 = 10138
- 71 + 10067 = 10138
- 101 + 10037 = 10138
- 131 + 10007 = 10138
- 197 + 9941 = 10138
- 251 + 9887 = 10138
Showing the first eight; more decompositions exist.
