Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 938406, here are decompositions:
- 13 + 938393 = 938406
- 19 + 938387 = 938406
- 37 + 938369 = 938406
- 47 + 938359 = 938406
- 59 + 938347 = 938406
- 83 + 938323 = 938406
- 97 + 938309 = 938406
- 113 + 938293 = 938406
Showing the first eight; more decompositions exist.
