Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1862, here are decompositions:
- 31 + 1831 = 1862
- 61 + 1801 = 1862
- 73 + 1789 = 1862
- 79 + 1783 = 1862
- 103 + 1759 = 1862
- 109 + 1753 = 1862
- 139 + 1723 = 1862
- 163 + 1699 = 1862
Showing the first eight; more decompositions exist.
