Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1007920, here are decompositions:
- 29 + 1007891 = 1007920
- 47 + 1007873 = 1007920
- 59 + 1007861 = 1007920
- 101 + 1007819 = 1007920
- 107 + 1007813 = 1007920
- 113 + 1007807 = 1007920
- 131 + 1007789 = 1007920
- 149 + 1007771 = 1007920
Showing the first eight; more decompositions exist.
