Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 138148, here are decompositions:
- 5 + 138143 = 138148
- 41 + 138107 = 138148
- 47 + 138101 = 138148
- 71 + 138077 = 138148
- 89 + 138059 = 138148
- 107 + 138041 = 138148
- 149 + 137999 = 138148
- 191 + 137957 = 138148
Showing the first eight; more decompositions exist.
