Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1814, here are decompositions:
- 3 + 1811 = 1814
- 13 + 1801 = 1814
- 31 + 1783 = 1814
- 37 + 1777 = 1814
- 61 + 1753 = 1814
- 67 + 1747 = 1814
- 73 + 1741 = 1814
- 151 + 1663 = 1814
Showing the first eight; more decompositions exist.
