Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1038128, here are decompositions:
- 109 + 1038019 = 1038128
- 127 + 1038001 = 1038128
- 199 + 1037929 = 1038128
- 211 + 1037917 = 1038128
- 271 + 1037857 = 1038128
- 337 + 1037791 = 1038128
- 571 + 1037557 = 1038128
- 631 + 1037497 = 1038128
Showing the first eight; more decompositions exist.
