Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 995820, here are decompositions:
- 19 + 995801 = 995820
- 29 + 995791 = 995820
- 37 + 995783 = 995820
- 73 + 995747 = 995820
- 83 + 995737 = 995820
- 101 + 995719 = 995820
- 107 + 995713 = 995820
- 151 + 995669 = 995820
Showing the first eight; more decompositions exist.
