Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8749944, here are decompositions:
- 17 + 8749927 = 8749944
- 23 + 8749921 = 8749944
- 41 + 8749903 = 8749944
- 53 + 8749891 = 8749944
- 97 + 8749847 = 8749944
- 103 + 8749841 = 8749944
- 107 + 8749837 = 8749944
- 127 + 8749817 = 8749944
Showing the first eight; more decompositions exist.
