Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1860, here are decompositions:
- 13 + 1847 = 1860
- 29 + 1831 = 1860
- 37 + 1823 = 1860
- 59 + 1801 = 1860
- 71 + 1789 = 1860
- 73 + 1787 = 1860
- 83 + 1777 = 1860
- 101 + 1759 = 1860
Showing the first eight; more decompositions exist.
