Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 18792, here are decompositions:
- 5 + 18787 = 18792
- 19 + 18773 = 18792
- 43 + 18749 = 18792
- 61 + 18731 = 18792
- 73 + 18719 = 18792
- 79 + 18713 = 18792
- 101 + 18691 = 18792
- 113 + 18679 = 18792
Showing the first eight; more decompositions exist.
