Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1038120, here are decompositions:
- 43 + 1038077 = 1038120
- 47 + 1038073 = 1038120
- 73 + 1038047 = 1038120
- 79 + 1038041 = 1038120
- 101 + 1038019 = 1038120
- 103 + 1038017 = 1038120
- 137 + 1037983 = 1038120
- 157 + 1037963 = 1038120
Showing the first eight; more decompositions exist.
