Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 69138, here are decompositions:
- 11 + 69127 = 69138
- 19 + 69119 = 69138
- 29 + 69109 = 69138
- 71 + 69067 = 69138
- 107 + 69031 = 69138
- 109 + 69029 = 69138
- 127 + 69011 = 69138
- 137 + 69001 = 69138
Showing the first eight; more decompositions exist.
