Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1844, here are decompositions:
- 13 + 1831 = 1844
- 43 + 1801 = 1844
- 61 + 1783 = 1844
- 67 + 1777 = 1844
- 97 + 1747 = 1844
- 103 + 1741 = 1844
- 151 + 1693 = 1844
- 181 + 1663 = 1844
Showing the first eight; more decompositions exist.
