Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 138416, here are decompositions:
- 13 + 138403 = 138416
- 43 + 138373 = 138416
- 67 + 138349 = 138416
- 79 + 138337 = 138416
- 97 + 138319 = 138416
- 127 + 138289 = 138416
- 277 + 138139 = 138416
- 337 + 138079 = 138416
Showing the first eight; more decompositions exist.
