Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 38212, here are decompositions:
- 11 + 38201 = 38212
- 23 + 38189 = 38212
- 29 + 38183 = 38212
- 59 + 38153 = 38212
- 173 + 38039 = 38212
- 359 + 37853 = 38212
- 401 + 37811 = 38212
- 431 + 37781 = 38212
Showing the first eight; more decompositions exist.
