Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 138292, here are decompositions:
- 3 + 138289 = 138292
- 41 + 138251 = 138292
- 53 + 138239 = 138292
- 83 + 138209 = 138292
- 101 + 138191 = 138292
- 113 + 138179 = 138292
- 149 + 138143 = 138292
- 179 + 138113 = 138292
Showing the first eight; more decompositions exist.
