Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1788, here are decompositions:
- 5 + 1783 = 1788
- 11 + 1777 = 1788
- 29 + 1759 = 1788
- 41 + 1747 = 1788
- 47 + 1741 = 1788
- 67 + 1721 = 1788
- 79 + 1709 = 1788
- 89 + 1699 = 1788
Showing the first eight; more decompositions exist.
