Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8725626, here are decompositions:
- 5 + 8725621 = 8725626
- 17 + 8725609 = 8725626
- 59 + 8725567 = 8725626
- 79 + 8725547 = 8725626
- 103 + 8725523 = 8725626
- 127 + 8725499 = 8725626
- 137 + 8725489 = 8725626
- 163 + 8725463 = 8725626
Showing the first eight; more decompositions exist.
