Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 138552, here are decompositions:
- 5 + 138547 = 138552
- 41 + 138511 = 138552
- 59 + 138493 = 138552
- 83 + 138469 = 138552
- 101 + 138451 = 138552
- 103 + 138449 = 138552
- 149 + 138403 = 138552
- 151 + 138401 = 138552
Showing the first eight; more decompositions exist.
