Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1038880, here are decompositions:
- 47 + 1038833 = 1038880
- 53 + 1038827 = 1038880
- 83 + 1038797 = 1038880
- 149 + 1038731 = 1038880
- 173 + 1038707 = 1038880
- 191 + 1038689 = 1038880
- 251 + 1038629 = 1038880
- 257 + 1038623 = 1038880
Showing the first eight; more decompositions exist.
