Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 138262, here are decompositions:
- 11 + 138251 = 138262
- 23 + 138239 = 138262
- 53 + 138209 = 138262
- 71 + 138191 = 138262
- 83 + 138179 = 138262
- 149 + 138113 = 138262
- 191 + 138071 = 138262
- 263 + 137999 = 138262
Showing the first eight; more decompositions exist.
