Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 18756, here are decompositions:
- 7 + 18749 = 18756
- 13 + 18743 = 18756
- 37 + 18719 = 18756
- 43 + 18713 = 18756
- 139 + 18617 = 18756
- 163 + 18593 = 18756
- 173 + 18583 = 18756
- 233 + 18523 = 18756
Showing the first eight; more decompositions exist.
