Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 138106, here are decompositions:
- 5 + 138101 = 138106
- 29 + 138077 = 138106
- 47 + 138059 = 138106
- 53 + 138053 = 138106
- 107 + 137999 = 138106
- 113 + 137993 = 138106
- 149 + 137957 = 138106
- 173 + 137933 = 138106
Showing the first eight; more decompositions exist.
