Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 138502, here are decompositions:
- 5 + 138497 = 138502
- 41 + 138461 = 138502
- 53 + 138449 = 138502
- 101 + 138401 = 138502
- 113 + 138389 = 138502
- 131 + 138371 = 138502
- 179 + 138323 = 138502
- 191 + 138311 = 138502
Showing the first eight; more decompositions exist.
