Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8738928, here are decompositions:
- 47 + 8738881 = 8738928
- 89 + 8738839 = 8738928
- 127 + 8738801 = 8738928
- 199 + 8738729 = 8738928
- 257 + 8738671 = 8738928
- 269 + 8738659 = 8738928
- 337 + 8738591 = 8738928
- 347 + 8738581 = 8738928
Showing the first eight; more decompositions exist.
